DESCRIPTION

The HCC40181B (extended temperature range)

and HCF40181B (intermediate temperature range)

are monolithic integrated circuits, available in 24-

lead dual in-line plastic or ceramic package and

plastic micro package. The HCC/HCF40181B is a

low-power four-bit parallel arithmetic logic unit

(ALU) capable of providing 16 binary arithmetic

operations on two four-bit words and16 logical func-

tions of two Boolean variables. The mode control

input M selects logical (M = High) or arithmetic (M =

Low) operation. The four select inputs (S0, S1, S2,

and S3) select thedesired logical or arithmetic func-

tions,which include AND, OR,NAND, NOR, and ex-

clusive-OR and-NOR in the logical mode, and

addition, subtraction, decrement, left-shift and

straight transfer in the arithmetic mode, according to

the truth table. The HCC/HCF40181B operation

may be interpreted with either active-low or active-

high data at the A andB word inputs and the function

outputs F, by using the appropriate truth table. The

HCC/HCF40181B contains logic for full look-ahead

carry operation for fast carry generation using the

carry-generate and carry-propagate outputs G and
