Voltage values, unless otherwise noted, are with respect to network ground terminal.2. This is the voltage between two emitters of a multiple-emitter transistor. This rating applies between inputs that go directly intothe same AND Or NAND gate in the functional block diagram.3. Ratings for MSI parts are given on the individual date sheets.unused inputs of positive-AND/NAND gatesFor optimum switching times and minimum noise susceptibility, unused inputs of AND or NAND gates should bemaintained at a voltage greater than VOH min (see tables of electrical characteristics), but not to exceed the absolutemaximum rating. This eliminates the distributed capacitance associated with the floating input, bond wire, and packagelead, and ensures that no degradation will occur in the propagation delay times. Some possible ways of handling unusedinputs are:a. Connect unused inputs to an independent supply voltage. Preferably, this voltage should be between VOH min and4.5 V. Series 54LS/74LS devices with diode inputs may be connected directly to VCC ..b. Connect unused inputs to a used input if maximum drive capability of the driving output will not be exceeded.Each additional input presents a full load to the driving output at a high-level voltage but adds no loading at alow-level voltage.c. Connect unused inputs to VCC through a '-kn resistor so that if a transient that exceeds the input maximumrating should occur, the impedance will be high enough to protect the input.

54174 FAMILIES OF COMPATIBLE TTL CIRCUITSinput-current requirementsInput-current requirements reflect worst-case conditions over the specified recommended operating free-air temperatureand VCC ranges. The table below shows maximum input current requirements and nominal base resistor values forstandard loads in each TTL series. A standard load is defined as an Input connected to a single emitter or diode that isassociated with a pull-up resistor having the value indicated in the table. However, some inputs are tied to more thanone input transistor (or diode). or the base-resistor values of some inputs have been changed either to reduceinput-current requirements or to improve performance. Therefore, the input-current requirements may vary. Consultthe electrical characteristics table for the particular device type to determine the input-current requirements of eachinput.SERIESSTANDARD INPUTS (ONE LOAD)tNOMINAL VALUE OF MAXIMUM HIGH-LEVEL MAXIMUM LOW-LEVELINPUT PULL-UP RESISTOR INPUT CURRENT INPUT CURRENT54/74 4 kn 40llA -1.6 rnA54A LS/74A LS 40 kn 20llA -0.1 rnA54AS/74AS 8 kn 20llA -0.5 rnA54H/74H 2.8 kn 50llA -2 rnA54L:j:54LS/74LS+40 kn 10llA -0.18 rnA8kn 20llA -0.8 rnA18 kn 20llA -0.4 rnA12 kn 20llA -0.2 rnA54S/74S 2.8 kn 501lA. -2 rnAt:o'';::'caEa...o'tot:- caa...Q)s::Q)C!)tSeries 54L and 54LS174LS have two different types of inputs as shown.Since low-level input current is primarily a function of the input base resistor, two or more inputs of the same NANDor AND gate may be tied together and still be considered one load at a low logic level, but at a high logic level, eachinput is an additional load.Currents into input terminals are specified as positive values.

EXPLANATION OF FUNCTION TABLESAmong the most complex function tables in this book are those of the shift registers. These embody most of thesymbols used in any of the function tables, plus more. Below is the function table of a 4-bit bidirectional universalshift register, e.g., type SN74194.INPUTSFUNCTION TABLEOUTPUTSMODE SERIAL PARALLELCLEAR '--- CLOCK °A °B Oc 00Sl SO LEFT RIGHT A B C 0L X X X X X X X X X L L L LH X X L X X X X X X °AO QBO QCO QDOH H H t X X a b c d a b c dH L H t X H X X X X H QAn QSn QCnH L H t X L X X X X L QAn QSn QCnH H L t H X X X X X QS n QCn QDn HH H L t L X X X X X QBn QCn QDn LH L L X X X X X X X QAO QBO QCO QDOThe first line of the table represents a synchronous clearing of the register and says that if clear is low, all four outputswill be reset low regardless of the other inputs. I n the following lines, clear is inactive (high) and so has no effect.The second line shows that so long as the clock input remains low (while clear is high). no other input has any effeCtand the outputs maintain the levels they assumed before the steady-state combination of clear high and clock low wasestablished. Since on other lines of the table only the rising transition of the clock is shown to be active, the second lineimplicitly shows that no further change in the outputs will occur while the clock remains high or on the high-to-Iowtransition of the clock.c:o0';:;CO... Eo'to-.5C6...CI)c:CI)C!)The third line of the table represents synchronous parallel loading of the register and says that if Sl and SO are bothhigh then, without regard to the serial input, the data entered at A will be at output OA, data entered at B will be at0B, and so forth, following a low-to-high clock transition.The fourth and fifth lines represent the loading of high- and low-level data, respectively, from the shift-right serial inputand the shifting of previously entered data one bit; data previously at OA is now at OB, the previous levels of OB andOc are now at Oc and OD respectively, and the data previously at OD is no longer in the register. This entry of serialdata and shift takes place on the low·to-high transition of the clock when Sl is low and SO is high and the levels atinputs A through D have no effect.The sixth and seventh lines represent the loading of high- and low-level data, respectively, from the shift-left serial inputand the shifting of previously entered data one bit; data previously at OB is now at OA, the previous levels of Oc andOD are now at Os and OC, respectively, and the data previously at OA is no longer in the register. This entry of serialdata and shift takes place on the low·to-high transition of the clock when Sl is high and SO is low and the levels atinputs A through D have no effect.The last I ine shows that as long as both mode inputs are low, no other input has any effect and, as in the second line,the outputs maintain the levels they assumed before the steady-state combination of clear high and both mode inputslow was established.TEXASINSTRUMENlSPOST OFFICE BOX 225012 • DALLAS, TEXAS 752651-19

EXPLANATION OF NEW LOGIC SYMBOLSby F. A. MannINTRODUCTIONThe International Electrotechnical Commission (I EC) has been developing a very powerful symboliclanguage that can show the relationship of each input of a digital logic circuit to each output withoutshowing explicitly the internal logic. At the heart of the system is dependency notation, which will beexplained in Section 4.The system was introduced in the USA in a rudimentary form in IEEE/ANSI Standard Y32.14-1973.Lacking at that time a complete development of dependency notation, it offered little more than asubstitution of rectangular shapes for the familiar distinctive shapes for representing the basic functionsof AND, OR, negation, etc. This is no longer the case.Internationally, Working Group 2 oflEC Technical Committee TC-3 is preparing a new document(Publication 617-12) that will consolidate the original work started in the mid 1960's and publishedin 1972 (Publication 117-15) and the amendments and supplements that have followed. Similarlyfor the USA, IEEE Committee sec 11.9 is revising the publication IEEE Std 91/ANSI Y32.14.Texas Instruments is participating in the work of both organizations and this Data Book introducesnew logic symbols in anticipation of the new standards. When changes are made as the standardsdevelop, future editions will take those changes into account.The following explanation of the new symbolic language is necessarily brief and greatly condensedfrom what the standards publications will finally contain. This is not intended to be sufficient forIIthose people who will be developing symbols for new devices. Itis primarily intended to make possiblethe understanding of the symbols used in this book; comparing the symbols with functional blockdiagrams and/or function tables will further help that understanding.2SYMBOL COMPOSITIONA symbol comprises an outline or a combination of outlines together with one or more qualifyingsymbols. The shape of the symbols is not significant. As shown in Figure 1, gener~1 qualifying symbolsare used to tell exactly what logical operation is performed by the elements. Table I shows the generalqualifying symbols used in this data book. Input lines are placed on the left and output lines areplaced on the right. When an exception is made to that convention, the direction of signal flow isindicated by an arrow as shown in Figure 11.All outputs of a single, unsubdivided element always have identical internal logic states determined bythe function of the element except when otherwise indicated by an a~sociated qualifying symbolor label inside the element.(/)15..cE>en(.).0,o..JTEXASINSTRUMENTSPOST OFFICE BOX 225012 • DALLAS.

There is at least one logic connection between the elements when theline common to their outlines is perpendicular to the direction of signal flow. The number oflogic connections between elements will be clarified by the use of qualifying symbols and this isdiscussed further under that topic. If no indications are shown on either side of the common line, itis assumed there is only one connection.IroCOrren'

EXPLANATION OF NEW LOGIC SYMBOLSA common output depending on all elements of the array can be shown as the output of a commonoutputelement. Its distinctive visual feature is the double line at its top. In addition the commonoutputelement may have other inputs as shown in Figure 3. The function of the common-outputelement must be shown by use of a general qualifying symbol.COMMON-OUTPUTELEMENT(must, like other elements,hive a qualifying symbol todenote its logic function).3 QUALIFYING SYMBOLSFIGURE 3 -ILLUSTRATION OF COMMON-OUTPUT ELEMENT3.1 General Qualifying SymbolsTable I shows the general qualifying symbols used in this data book. These characters are placed nearthe top center or the geometric center of a symbol or symbol element to define the basic functionof the device represented by the symbol or of the element.3.2 Qualifying Symbols for Inputs and OutputsQualifying symbols for inputs and outputs are shown in Table" and will be familiar to most userswith the possible exception of the logic polarity and analog signal indicators. The older logic negationindicator means that the external 0 state produces the internal 1 state. The internal 1 state means theactive state_ Logic negation may be used in pure logic diagrams; in order to tie the external 1 and 0logic states to the levels H (high) and L (low), a statement of whether positive logic (1 = H, 0 = L) ornegative logic (1 = L, 0 = H) is being used is required or must be assumed. Logic polarity indicatorseliminate the need for calling out the logic convention and are used in this data book in the symbologyfor actual devices_ The presence of the triangular polarity indicator indicates that the L logic level willproduce the internal 1 state (the active state) or that, in the case of an output, the internal 1 state willproduce the external L level. Note how the active direction of transition for a dynamic input isindicated in positive logic, negative logic, and with polarity indication.•en15 .c .E>en(,).s,o...ITEXASINSTRUMENlS 4-7POST OFFICE BOX 225012 • DALLAS.

EXPLANATION OF NEW LOGIC SYMBOLSThe application of internal inputs and outputs requires an understanding of dependency notation,which is explained in Section 4.In an array of elements, if the same general qualifying symbol and the same qualifying symbolsassociated with inputs and outputs would appear inside each of the elements of the array, thesequalifying symbols are usually shown only in the first element. This is done to reduce clutter and tosave time in recognition. Similarly, large identical elements that are subdivided into smaller elementsmay each be represented by an unsubdivided outline. The SN54 LS440 symbol illustrates this principle.3.3 Symbols Inside the OutlineTable III shows some symbols used inside the outline. Note particularly that open-collector, openemitter,and three-state outputs have distinctive symbols. Also note that an EN input affects all of theoutputs of the circuit and has no effect on inputs. When an enable input affects only certain outputsandlor affects one or more inputs, a form of dependency notation will indicate this (see 4.9). Theeffects of the EN input on the various types of outputs are shown.It is particularly important to note that a D input is always the data input of a storage element. Atits internal 1 state, the D input sets the storage element to its 1 state, and at its internal 0 state it resetsthe storage element to its 0 state.The binary grouping symbol will be explained more fully in Section 8. Binary-weighted inputs arearranged in order and the binary weights of the least-significant and the most-significant lines areindicated by numbers. In this data book weights of input and output lines will be represented bypowers of two usually only when the binary grouping symbol is used, otherwise, decimal numbers willbe used. The grouped inputs generate an internal number on which a mathematical function can beperformed or that can be an identifying number for dependency notation. See Figure 28. A frequentuse is in addresses for memories.Reversed in direction, the binary grouping symbol can be used with outputs. The concept-is analogousto that for the inputs and the weighted outputs will indicate the internal number assumed to bedeveloped within the circuit.Other symbols are used inside the outlines in this data book in accordance with the I Eell E EEstandards but are not shown here. Generally,these are associated with arithmetic operations and areself-explanatory.IIen'0.cE>en(.)os,o..JWhen nonstandardized information is shown inside an outline, it is usually enclosed in square brackets[like these] .TEXASINSTRUMENTS 4-11POST OFFICE BOX 225012 • DALLAS, TEXAS 75265

EXPLANATION OF NEW LOGIC SYMBOLS4 DEPENDENCY NOTATION4.1 General ExplanationDependency notation is the powerful tool that sets the IEC symbols apart from previous systems andmakes compact, meaningful, symbols possible. It provides the means of denoting the relationshipbetween inputs, outputs, or inputs and outputs without actually showing all the elements and interconnectionsinvolved. The information provided by dependency notation supplements that providedby the qualifying symbols for an element's function.In the convention for the dependency notation, use will be made of the terms "affecting" and"affected". In cases where it is not evident which inputs must be considered as being the affectingor the affected ones (e.g., if they stand in an AND relationship), the choice may be made in anyconvenient way.So far, ten types of dependency have been defined and all of these are used in this data book. They arelisted below in the order in which they are presented and are summarized in Table IV following4.11.roCO5'en-

EXPLANATION OF NEW LOGIC SYMBOLSIn Figure 4 input b is ANDed with input a and the complement of b is ANDed with c. The letter G has·been chosen to indicate AND relationships and is placed at input b, inside the symbol. A numberconsidered appropriate by the symbol designer (1 has been used here) is placed after the letter G andalso at each affected input.

When the Gm input or outputstands at its 0 state, all inputs and outputs affected by Gm stand at their internal 0 states.IIen'0..cE>en(.).s,o-oJTEXASINSTRUMENTS 4-13POST OFFICE BOX 225012 • DALLAS. TEXAS 75265

EXPLANATION OF NEW LOGIC SYMBOLS4.3 Conventions for the Application of Dependency Notation in GeneralThe rules for applying dependency relationships in general follow the same pattern as was illustratedfor G dependency.Application of dependency notation is accomplished by:1) labeling the input (or output) affecting other inputs or outputs with the letter symbolindicating the relationship involved (e.g., G for AND) followed by an identifying number,appropriately chosen, and2) ,labeling each input or output affected by that affecting input (or output) with that samenumber.I f it is the complement ofthe internal logic state ofthe affecting input or output that does the affecting,then a bar is placed over the"identifying numbers at the affected inputs or outputs. See Figure 4.If two affecting inputs or outputs have the same letter and same identifying number, they stand in anOR relationship to each other. See Figure 7.a~G-'-b G1c 1a~~1b &cFIGURE 7 - OR'ED AFFECTING INPUTSIIroceoo(J)-

EXPLANATION OF NEW LOGIC SYMBOLSWhen an Nm input or output stands at its internal 1 state, the internal logic state of each input and eachoutput affected by Nm is the complement of what it would otherwise be. When an Nm input oroutput stands at its internal 0 state, all inputs and outputs affected by Nm stand at their normallydefined internal logic states.4.6 Z (Interconnection) DependencyThe symbol denoting interconnection dependency is the letter Z.Interconnection dependency is used to indicate the existence of internal logic connections betweeninputs, outputs, internal inputs, and/or internal outputs.The internal logic state of an input or output affected by a Zm input or output will be the same as theinternal logic state of the Zm input or output, unless modified by additional dependency notation.See Figure 11.a-f~tb-'W'where~=-{>-E=z}--a-W'where-[}-=-

EXPLANATION OF NEW LOGIC SYMBOLS4.7 C (Control) DependencyThe symbol denoting control dependency is the letter C.Control inputs are usually used to enable or disable the data (0, J, K, R, or S) inputs of storageelements. They may take on their internal 1 states (be active) either statically or dynamically. In thelatter case the dynamic input symbol is used as shown in the third example of Figure 12.a-fc7b-r Oat' _a~lb C2 == b 1 C2 = b &a~& S-c 1.20 c 20 c R/- - -Note AND relationship of a and ba~-G1b 1,20c C2b a~-& Sc& R-a 120~b 1,20c G1d C2a~&;;'1' -.:..b & & Sc & Rd -Input c selects which of a or b is stored when d goes low.FIGURE 12 - C (CONTROL) DEPENDENCYWhen a Cm input or output stands at its internal 1 state, the inputs affected by Cm have their normallydefined effect on the function of the element,. i.e., these inputs are enabled.

ENm are also disabled. Opencollectoroutputs are turned off, three-state outputs stand at their normally defined internal logicstates but externally exhibit high impedance, and all other outputs (e.g., totem-pole outputs) stand attheir internal 0 states.4.10 M (Mode) DependencyThe symbol denoting mode dependency is the letter M.Mode dependency is used to indicate that the effects of particular inputs and outputs of an elementdepend on the mode in which the element is operating.If an input or output has the same effect in different modes of operation, the identifying numbersof the relevant affecting Mm inputs will appear in the label of that affected input or output betweenparentheses and separated by solidi. See Figure 19.4.10.1 M Dependency Affecting InputsM dependency affects inputs the same as C dependency. When an Mm input or Mm output stands atits internal 1 state, the inputs affected by this Mm input or Mm output have their normally definedeffect on the function of the element, i.e., the inputs are enabled.When an Mm input or Mm output stands at its internal 0 state, the inputs affected by this Mm input orMm output have no effect on the function of the element. When an affected input has several sets oflabels separated by solidi (e.g., C4/2~/3+), any set in which the identifying number of the Mm inputor Mm output appears has no effect and is to be ignored. This represents disabling of some of thefunctions of a multifunction input.IICI)"0.cE>en.2C)o..J, TEXASINSTRUMENTS 4-19POST OFFICE BOX 225012 • DALLAS, TEXAS 75265

EXPLANATION OF NEW LOGIC SYMBOLSThe circuit in Figure 15 has two inputs, band c, that control which one of four modes (0, 1,2, or 3)will exist at any time. Inputs d, e, and fare D inputs subject to dynamic control (clocking) by the ainput. The numbers 1 and 2 are in the series chosen to indicate the modes so inputs e and f are onlyenabled in mode 1 (for parallel loading) and input d is only enabled in mode 2 (for serial loading).Note that input a has three functions. It is the clock for entering data. In mode 2, it causes rightshifting of data, which means a shift away from the control block. In mode 3, it causes the contents ofthe register to be incremented by one count.1,4DNote that all operations are synchronous.In MODE 0 (b = 0, c = 01, the outputsremain at their existing states as noneof the inputs has an effect.In MODE 1 (b = 1, ~ = 01, parallel loadingtakes place thru inputs e and f.In MODE 2 (b = 0, c = 11, shifting downand serial loading thru input d take place.'In MODE 3 (b = c = 11, counting up byincrement of 1 per clock pulse takes place.FIGURE 15 -M (MODEl DEPENDENCY AFFECTING INPUTS4.10.2 M Dependency Affecting OutputsWhen an Mm input or Mm output stands at its internal 1 state, the affected outputs stand at theirnormally defined internal logic states, Le., the outputs are enabled.IIro«:25'CJ)'

EXPLANATION OF NEW LOGIC SYMBOLSIn Figure 17, if input a stands at its internal 1state establish ing mode 1, output b will standat its internal 1 state only when the contentof the register equals 9. Since output b islocated in the common-control block with nodefined function outside of mode 1, the stateof this output outside of mode 1 is not definedby the symbol.a-1M1II~1CT=9 ~bIII~FIGURE 17 - DISABLING AN OUTPUT OF THECOMMON~ONTROLBLOCKIn Figure 18, if input a stands at its internal 1state establishing mode 1, output b will standat its internal 1 state only when the contentof the register equals 15. If input a stands atits internal 0 state, output b will stand at itsinternal 1 state only when the content of theregister equals O.III(IIISIn Figure 19 inputs a and b are binary weightedto generate the numbers 0, 1, 2, or 3.

EXPLANATION OF NEW LOGIC SYMBOLSAddress dependency provides a clear representation of those elements, particularly memories, that useaddress control inputs to select specified sections of a multidimensional array. Such a section of amemory array is usually called a word. The purpose of address dependency is to allow a symbolicpresentation of the entire array. An input of the array shown at a particular element of this generalsection is common to the corresponding elements of all selected sections of the array. An outputof the array shown at a particular element of this general section is the result of the OR function ofthe outputs of the corresponding elements of selected sections. If the label of an output of the arrayshown at a particular element of this general section indicates that this output is an open-circuitoutput or a three-state output, then this indication refers to the output of the array and not to thoseof the sections of the array.Inputs that are not affected by any affecting address input have their normally defined effect on allsections of the array, whereas inputs affected by an address input have their normally defined effectonly on the section selected by that address input.An affecting address input is labelled with the letter A followed by an identifying number thatcorresponds with the address of the particular section of the array selected by this input. Withinthe general section presented by the symbol, inputs and outputs affected by an Am input are labelledwith the letter A, which stands for the identifying numbers, i.e., the addresses, of the particularsections.•bcdIro(Qr;"en-

EXPLANATION OF NEW LOGIC SYMBOLSIf there are several sets of affecting Am inputs for the purpose of independent and possiblysimultaneous access to sections of the array, then the letter A is modified to 1A, 2A, ... Because theyhave access to the same sections of the array, these sets of A inputs may have the same identifyingnumbers.Figure 21 is another illustration of the concept.RAM16X4EN)A~C1FIGURE 21FIGURE 21 - ARRAY OF 16 SECTIONS OF FOUR TRANSPARENT LATCHES WITH 3·STATE OUTPUTSCOMPRISING A 16·WORD X 4·BIT RANDOM-ACCESS MEMORYTABLE IV - SUMMARY OF DEPENDENCY NOTATIONTYPE OF LETTER AFFECTING INPUT AFFECTING INPUTDEPENDENCY SYMBOL * AT ITS 1-STATE AT ITS O-STATEAddress A Perm its action (address selected) Prevents action (address not selected)Control C Permits action Prevents actionPrevents action of inputs.ooutputs off.Enable EN Permits action '\l outputs at external high impedance,no change in internal logic state.Other outputs at internal 0 state.AND G Permits action Imposes 0 stateMode M Permits action (mode selected) Prevents action (mode not selected)Negate (X·O R) N Complements state No effectRESETSETRSAffected output reacts asit would to S = 0, R = 1Affected output reacts asit would to S = 1, R = 0No effectNo effectOR V Imposes 1 state Permits actionInterconnection Z Imposes 1 state Imposes 0 stateIItJ)"0.cE>en.~Clo-I"These letter symbols appear at the AFFECTING input (or output) and are followed by a number.

EXPLANATION OF NEW LOGIC SYMBOLS5 BISTABLE ELEMENTSThe dynamic input symbol, the postponed output symbol, and dependency notation provide the toolsto differentiate four main types of bistable elements and make synchronous and asynchronous inputseasily recognizable. See Figure 22. The first column shows the essential distinguishing features; theother columns show examples.Transparent latches have a . level-operated control input. The 0 input is active as long as the C inputis at its internal 1 state. The outputs respond immediately. Edge-triggered elements accept data from0, J, K, R~ or S inputs on the active transition of C. Pulse-triggered elements require the setup of databefore the start of the control pulse; the C input is considered static since the data must be maintainedas long as C is at its 1 state. The output is postponed until C returns to its 0 state. The data-lock-outelement is similar to the pulse-triggered version except that the C input is considered dynamic in thatshortly after C goes through its active transition, the data inputs are disabled and data does not have tobe held. However, the output is still postponed until the C input returns to its initial external level.IroCCc:ren

EXPLANATION OF NEW LOGIC SYMBOLS6 CODERSThe general symbol for a coder or codeconverter is shown in Figure 23. X and Ymay be replaced by appropriate indicationsof the code used to represent the informationat the inputs and at the outputs,respectively.FIGURE 23 - CODER GENERAL SYMBOLIndication of code conversion is based on the following rule:Depending on the input code, the internal logic states of the inputs determine an internal value.This value· is reproduced by the internal logic states of the outputs, depending on the outputcode.The indication of the relationships between the internal logic states of the inputs and the internalvalue is accomplished by:1) labelling the inputs with numbers. In this case the internal value equals the sum of theweights associated with those inputs that stand at their internal 1-state, or by2) replacing X by an appropriate indication of the input code and labelling the inputs withcharacters that refer to this code.The relationships between the internal value and the internal logic states of the outputs areindicated by:1 ) labelling each output with a list of numbers representing those i.nternal values that lead to IIthe internal 1-state of that output. These numbers shall be separated by solidi as in Figure ~24. This labelling may also be applied when Y is replaced by a letter denoting a type ofdependency (see Section 7). If a continuous range of internal values produces the internal 1state of an output, this can be indicated by two numbers that are inclusively the beginningand the end of the range, with these two numbers separated by three dots, e.g., 4 ... 9 =4/5/6/7 /8/9, or by2) replacing Y by an appropriate indication of the output code and labelling the outputs withcharacters that refer to this code as in Figure 25.Alternatively, the general symbol may be used together with an appropriate reference to a table inwhich the relationship between the inputs and outputs is indicated.

However, there arecases in which this method of presentation is not advantageous. In those cases the input may be shownonce with the different sets of labels separated by solidi. See Figure 29.
