74HC283中文资料DATA SHEETProduct speci?cationFile under Integrated Circuits, IC06December 1990INTEGRATED CIRCUITS74HC/HCT2834-bit binary full adder with fast carryFor a complete data sheet, please also download:The IC06 74HC/HCT/HCU/HCMOS Logic Family Specifications ?The IC06 74HC/HCT/HCU/HCMOS Logic Package Information ?The IC06 74HC/HCT/HCU/HCMOS Logic Package OutlinesFEATURESHigh-speed 4-bit binary addition ?Cascadable in 4-bit increments ?Fast internal look-ahead carry ?Output capability: standard ?I CC category: MSI GENERAL DESCRIPTION The 74HC/HCT283 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.The 74HC/HCT283 add two 4-bit binary words (A n plus B n )plus the incoming carry. The binary sum appears on the sum outputs (∑1 to ∑4) and the out-going carry (C OUT )according to the equation:C IN +(A 1+B 1)+2(A 2+B 2)++4(A 3+B 3)+8(A 4+B4)==∑1+2∑2+4∑3+8∑4+16C OUT Where (+)=plus.Due to the symmetry of the binary add function, the “283”can be used with either all active HIGH operands (positive logic) or all active LOW operands (negative logic); see functiontable. In cas e of all active LOW operands the results ∑1 to ∑4 and C OUT should be interpreted also as active LOW. With active HIGH inputs, C IN must be held LOW when no “carry in” is intended. Interchanging inputs of equal weight does not affect the operation, thus C IN , A 1,B 1 can be assigned arbitrarily to pins 5, 6, 7, etc.See the “583” for the BCD version.QUICK REFERENCE DATAGND =0 V; T amb =25°C; t r =t f =6 ns Notes1.C PD is used to determine the dynamic power dissipation (P D in μW):P D =C PD ×V CC 2×f i +∑(C L ×V CC 2×f o ) where:f i =input frequency in MHz f o =output frequency in MHz ∑(C L ×V CC 2×f o )=sum of outputs C L =output load capacitance in pF V CC =supply voltage in V2.For HC the condition is V I =GND to V CCFor HCT the condition is V I =GND to V CC ?1.5 V SYMBOL PARAMETER CONDITIONS TYPICAL UNITHCHCT t PHL / t PLHpropagation delay C L =15 pF; V CC =5 VC IN to ∑11615ns C IN to ∑21821ns C IN to ∑32023ns C IN to ∑42327ns A n or B n to ∑n 2125ns C IN to C OUT 2023ns A n or B n to C OUT2024ns C I input capacitance3.5 3.5pF C PD power dissipation capacitance per packagenotes 1 and 28892pFORDERING INFORMATIONSee“74HC/HCT/HCU/HCMOS Logic Package Information”.PIN DESCRIPTIONPIN NO.SYMBOL NAME AND FUNCTION4, 1, 13, 10∑1 to∑4sum outputs5, 3, 14, 12A1 to A4 A operand inputs6, 2, 15, 11B1 to B4 B operand inputs7C IN carry input8GND ground (0 V)9C OUT carry output16V CC positive supply voltageFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.Fig.4 Functional diagram.FUNCTION TABLEPINS C IN A1A2A3A4B1B2B3B4∑1∑2∑3∑4C OUT EXAMPLE(2) logic levels L L H L H H L L H H H L L Hactive HIGH00101100111001(3)active LOW11010011000110(4)Note1.H=HIGH voltage levelL=LOW voltage level2.example10011010-----100113.for active HIGH, example=(9+10=19)4.for active LOW, example=(carry+6+5=12)Fig.5 Logic diagram.DC CHARACTERISTICS FOR 74HCFor the DC characteristics see“74HC/HCT/HCU/HCMOSLogic Family Specifications”.

The third stage adder (A 2, B 2,∑ 2) is used simply as means oftransferring the carry into the fourth stage (via A 2 and B 2)and transferring the carry from the second stage on ∑2.Note that as long as long as A 2 and B 2 are the same, HIGH or LOW, they do not influence ∑2.

Figure 9 shows a method of implementing a 5-input encoder, where the inputs are equally weighted. The outputs ∑0,∑1 and ∑ 2produce a binary number equal to the number inputs (I 1 to I 5) that are HIGH. Figure 10 shows a method ofimplementing a 5-input majority gate. When three or more inputs (I 1 to I 5) are HIGH, the output M 5 is HIGH.PACKAGE OUTLINESSee “74HC/HCT/HCU/HCMOS Logic Package Outlines”.。

HD74AC283/HD74ACT2834-bit Binary Full Adder with Fast CarryADE-205-388 (Z)1st. EditionSep. 2000 DescriptionThe HD74AC283/HD74ACT283 high-speed 4-bit binary full adder with internal carry lookahead acceptstwo 4-bit binary works (A0 – A3, B– B3) and a Carry input (C). It generates the binary Sum outputs (S–S 3) and the Carry output (C4) from the most significant bit. The HD74AC283/HD74ACT283 will operatewith either active High or active Low operands (positive or negative logic). Features• Outputs Source/Sink 24 mA• HD74ACT283 has TTL-Cmpatible InputsPin ArrangementHD74AC283/HD74ACT2832Logic SymbolPin NamesA 0 – A 3 A Operand InputsB 0 – B 3 B Operand InputsC 0Carry Input S 0 – S 3Sum Outputs C 4Carry OutputFunctional DescriptionThe HD74AC283/HD74ACT283 adds two 4-bit binary words (A plus B) plus the incoming Carry (C 0).The binary sum appears on the Sum (S 0 – S 3) and outgoing carry (C 4) outputs. The binary weight of the various inputs and outputs is indicated by the subscript numbers, representing powers of two.20 (A 0 + B 0 + C 0) + 21 (A 1 + B 1) + 22 (A 2 + B 2) + 23 (A 3 + B 3) = S 0 + 2S 1 + 4S 2 + 8S 3 + 16C 4Where (+) = plusInterchanging inputs of equal weight does not affect the operation. Thus C 0, A 0, B 0 can be arbitrarily assigned to pins 5, 6 and 7 for DIPS. Due to the symmetry of the binary add function, the HD74AC283/HD74ACT283 can be used either with all inputs and outputs active High (positive logic) or with all inputs and outputs active Low (negative logic). See Figure a. Note that if C 0 is not used it must be tied Low for active High logic or tied High for active Low logic.Due to pin limitations, the intermediate carries of the HD74AC283/HD74ACT283 are not brought out for use as inputs or outputs. However, other means can be used to effectively insert a carry into, or bring a carry out from, an intermediate stage. Figure b shows how to make a 3-bit adder. Tying the operand inputs of the fourth adder (A 3, B 3) Low makes S 3 dependent only on, and equal to, the carry from the third ing somewhat the same principle Figure c shows a way of dividing the HD74AC283/HD74ACT283 into a 2-bit and a 1-bit adder. The third stage adder (A 2, B 2, S 2) is used merely as a means of getting a carry (C 10) signal into the fourth stage (via A 2 and B 2) and bringing out the carry from the second stage on S 2.Note that as long as A 2 and B 2 are the same, whether High or Low, they do not influence S 2. Similarly,when A 2 and B 2 are the same the carry into the third stage does not influence the carry out of the thirdHD74AC283/HD74ACT2833stage. Figure d shows a method of implementing a 5-input encoder, where the inputs are equally weighted.The outputs S 0, S 1 and S 2 present a binary number equal to the number of inputs I 1 – I 5 that are true. Figure e shows one method of implementing a 5-input majority gate. When three or more of the inputs I 1 – I 5 are true, the output M 5 is true.Fig. a Active HIGH varsus Active LOW InterpretationC 0A 0A 1A 2A 3B 0B 1B 2B 3S 0S 1S 2S 3C 4Logic levels L L H L H H L L H H H L L H Active HIGH 00101100111001Active LOW1111111Active HIGH: 0 + 10 + 9 = 3 + 16Active LOW: 1 + 5 + 6 = 12 + 0Fig. b 3-bit AdderFig. c 2-bit and 1-bit addersHD74AC283/HD74ACT283Fig. d 5-Input EncoderFig. e 5-Input Majority Gate 4HD74AC283/HD74ACT2835Logic DiagramDC Characteristics (unless otherwise specified)ItemSymbol Max Unit ConditionMaximum quiescent supply current I CC 80µA V IN = V CC or ground, V CC = 5.5 V,Ta = Worst caseMaximum quiescent supply current I CC 8.0µA V IN = V CC or ground, V CC = 5.5 V,Ta = 25°CMaximum I CC /input (HD74ACT283)I CCT1.5mAV IN = V CC – 2.1 V, V CC = 5.5 V,Ta = Worst caseHD74AC283/HD74ACT2836AC Characteristics: HD74AC283Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Propagation delay t PLH3.3 1.011.515.0 1.016.5nsC 0 to S n5.0 1.09.511.5 1.012.5Propagation delay t PHL 3.3 1.010.514.0 1.015.5ns C 0 to S n5.0 1.08.510.5 1.011.5Propagation delay t PLH 3.3 1.014.017.0 1.018.5ns A n or B n to S n 5.0 1.011.513.5 1.014.5Propagation delay t PHL 3.3 1.013.516.5 1.018.0ns A n or B n to S n 5.0 1.011.013.0 1.014.0Propagation delay t PLH 3.3 1.09.512.5 1.015.5ns C 0 to C 45.0 1.07.59.5 1.010.5Propagation delay t PHL 3.3 1.010.013.0 1.014.0ns C 0 to C 45.0 1.08.010.0 1.011.0Propagation delay t PLH 3.3 1.011.514.5 1.016.0ns A n or B n to C 4 5.0 1.09.511.5 1.012.5Propagation delay t PHL 3.3 1.012.015.0 1.016.5ns A n or B n to C 4 5.01.010.012.01.013.0Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC283/HD74ACT2837AC Characteristics: HD74ACT283Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Propagation delay C 0 to S nt PLH 5.0 1.011.513.5 1.014.5ns Propagation delay C 0 to S nt PHL 5.0 1.010.012.0 1.013.0ns Propagation delay A n or B n to S n t PLH 5.0 1.013.015.0 1.016.5ns Propagation delay A n or B n to S n t PHL 5.0 1.012.014.0 1.015.5ns Propagation delay C 0 to C 4t PLH 5.0 1.09.011.0 1.012.0ns Propagation delay C 0 to C 4t PHL 5.0 1.010.012.0 1.013.0ns Propagation delay A n or B n to C 4t PLH 5.0 1.011.013.0 1.014.0ns Propagation delay A n or B n to C 4t PHL5.01.011.513.51.014.5nsNote:1.Voltage Range 5.0 is 5.0 V ± 0.5 VCapacitanceItemSymbol Typ Unit Condition Input capacitanceC IN 4.5pF V CC = 5.5 V Power dissipation capacitanceC PD60.0pFV CC = 5.0 VHD74AC283/HD74ACT283 Package Dimensions8HD74AC283/HD74ACT2839HD74AC283/HD74ACT28310Cautions1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

HD74HC2834-bit Binary Full AdderDescription) is obtained from the fourth bit. The sun () outputs are provided for each bit and the resultant carry (C4This adder features full internal look ahead across all four bits. This provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including the carry, is implemented in its true for meaning that the end-around carry can be accomplished without the need for logic or level inversion.Features• High Speed Operation: t pd = 19 ns typ (C L = 50 pF)• High Output Current: Fanout of 10 LSTTL Loads• Wide Operating Voltage: V CC = 2 to 6 V• Low Input Current: 1 µA max• Low Quiescent Supply Current: I CC (static) = 4 µA max (Ta = 25°C)HD74HC2832Function TableOutputsInputs When C 0 = L/When C 2 = L When C 0 = H/When C 2 = H A 1/A 3B 1/B 3A 2/A 4B 2/B 4∑1/∑3∑2/∑4C 2/C 4∑1/∑3∑1/∑4C 2/C 4L L L L L L L H L L H L L L H L L L H L L H L L H L L L H L H H L L L H L H H L L L H L L H L H H L H L H L H H L L L H L H H L H H L L L H H H H L L L H H L H L L L H L H L H H L H L L H H H L L L H L H L H H H L L L H H H L H L L H H L H L L H H L L H H L H H L H H H L H L H H L H H H H L H L H H HHHHLHHHHHH :high level L :low levelNote:Input conditions at A 1, B 1, A 2, B 2, and C 0 are used to determine outputs ∑1 and ∑2 and the value of theinternal carry C 2.

The sun () outputs are provided for each bit and the resultant carry (C4This adder features full internal look ahead across all four bits. This provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including the carry, is implemented in its true for meaning that the end-around carry can be accomplished without the need for logic or level inversion.Features• High Speed Operation: t pd = 19 ns typ (C L = 50 pF)• High Output Current: Fanout of 10 LSTTL Loads• Wide Operating Voltage: V CC = 2 to 6 V• Low Input Current: 1 µA max• Low Quiescent Supply Current: I CC (static) = 4 µA max (Ta = 25°C)HD74HC2832Function TableOutputsInputs When C 0 = L/When C 2 = L When C 0 = H/When C 2 = H A 1/A 3B 1/B 3A 2/A 4B 2/B 4∑1/∑3∑2/∑4C 2/C 4∑1/∑3∑2/∑4C 2/C 4L L L L L L L H L L H L L L H L L L H L L H L L H L L L H L H H L L L H L H H L L L H L L H L H H L H L H L H H L L L H L H H L H H L L L H H H H L L L H H L H L L L H L H L H H L H L L H H H L L L H L H L H H H L L L H H H L H L L H H L H L L H H L L H H L H H L H H H L H L H H L H H H H L H L H H HHHHLHHHHHH :high level L :low levelNote:Input conditions at A 1, B 1, A 2, B 2, and C 0 are used to determine outputs ∑1 and ∑2 and the value of theinternal carry C 2.

HD74AC283/HD74ACT2834-bit Binary Full Adder with Fast CarryREJ03D0267–0200Z(Previous ADE-205-388 (Z))Rev.2.00Jul.16.2004 DescriptionThe HD74AC283/HD74ACT283 high-speed 4-bit binary full adder with internal carry lookahead accepts two 4-bitbinary works (A0 – A3, B– B3) and a Carry input (C). It generates the binary Sum outputs (S– S3) and the Carryoutput (C4) from the most significant bit. The HD74AC283/HD74ACT283 will operate with either active High or active Low operands (positive or negative logic).Features•Outputs Source/Sink 24 mA•HD74ACT283 has TTL-Cmpatible Inputs•Ordering Information: Ex.

The binary sumappears on the Sum (S0 – S3) and outgoing carry (C4) outputs. The binary weight of the various inputs and outputs isindicated by the subscript numbers, representing powers of two.20 (A0 + B+ C) + 21 (A1+ B1) + 22 (A2+ B2) + 23 (A3+ B3) = S+ 2S1+ 4S2+ 8S3+ 16C4Where (+) = plusInterchanging inputs of equal weight does not affect the operation. Thus C0, A, Bcan be arbitrarily assigned to pins 5,6 and7 for DIPS. Due to the symmetry of the binary add function, the HD74AC283/HD74ACT283 can be used either with all inputs and outputs active High (positive logic) or with all inputs and outputs active Low (negative logic). See Figure a. Note that if Cis not used it must be tied Low for active High logic or tied High for active Low logic.Due to pin limitations, the intermediate carries of the HD74AC283/HD74ACT283 are not brought out for use as inputs or outputs. However, other means can be used to effectively insert a carry into, or bring a carry out from, anintermediate stage. Figure b shows how to make a 3-bit adder. Tying the operand inputs of the fourth adder (A3, B3)Low makes S3dependent only on, and equal to, the carry from the third adder. Using somewhat the same principle Figure c shows a way of dividing the HD74AC283/HD74ACT283 into a 2-bit and a 1-bit adder. The third stage adder(A2, B2, S2) is used merely as a means of getting a carry (C10) signal into the fourth stage (via A2and B2) and bringingout the carry from the second stage on S2. Note that as long as A2and B2are the same, whether High or Low, they donot influence S2. Similarly, when A2and B2are the same the carry into the third stage does not influence the carry outof the third stage. Figure d shows a method of implementing a 5-input encoder, where the inputs are equally weighted.The outputs S0, S1and S2present a binary number equal to the number of inputs I1– I5that are true. Figure e shows onemethod of implementing a 5-input majority gate. When three or more of the inputs I1 – I5are true, the output M5is true.Fig. a Active HIGH varsus Active LOW InterpretationC0AA1A2A3BB1B2B3SS1S2S3C4Logic levels L L H L H H L L H H H L L H Active
