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
EY

P for the four bits of the HCC/HCF40181B. Use of
the HCC/HCF40182B look-ahead carry generator
in conjunction with multiple HCC/HCF40181B's per-
mits high-speed arithmetic operations on long
words. A ripple carry output C
n + 4
is available for use
in systems where speed is not of primary import-
ance. Also included in the HCC/HCF40181B is a
comparator output A = B, which assumes a high
level whenever the two four-bit input words A and B
are equal and the device is in the subtract mode. In
addition, relative magnitude information may be
derived from the carry-in input C
n
and ripple carry-
out output C
n + 4
by placing the unit in the subtract
mode and externally decoding using the information
in table II. The HCC/HCF40181B is similar to indus-
try types MC 14581 and 74181.
