DESCRIPTION
The HCC40181B (extended temperature range)
and HCF40181B (intermediate temperature range)
are monolithic integrated circuits, availablein 24-
lead dual in-line plasticor ceramic package and
plastic micro package. The HCC/HCF40181Bisa
low-power four-bit parallel arithmetic logic unit
(ALU) capableof providing 16 binary arithmetic
operationson two four-bit words and16 logicalfunc-
tionsof two Boolean variables. The mode control
inputM selects logical(M= High)or arithmetic (M=
Low) operation. The four select inputs (S0, S1, S2,
and S3) select thedesired logicalor arithmetic func-
tions, whichinclude AND, OR, NAND, NOR,and ex-
clusive-OR and-NORin the logical mode, and
addition, subtraction, decrement, left-shift and
straight transferin the arithmetic mode, accordingto
the truth table. The HCC/HCF40181B operation
maybe interpreted with either active-lowor active-
high dataat the AandB word inputsand the function
outputsF,by using the appropriate truth table. The
HCC/HCF40181B contains logicforfull look-ahead

for the four bitsof the HCC/HCF40181B. Useofthe HCC/HCF40182B look-ahead carry generator conjunction with multiple HCC/HCF40181B’s per-
mits high-speed arithmetic operations on long
words.A ripple carry output Cn+4is available for use systems where speedis notof primary import-
ance. Also includedin the HCC/HCF40181Bisa
comparator outputA=B, which assumesa high
level whenever the two four-bit input wordsA andB
are equal and thedeviceisin the subtract mode.In
addition, relative magnitude information may be
derived from the carry-in inputCn and ripple carry-
out output Cn+4by placing the unitin the subtract
mode and externally decoding usingthe information tableII. The HCC/HCF40181Bis similarto indus-
try types MC 14581 and 74181.
