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 and 16 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 the desired 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 and B 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
