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 twofour-bitwords and16logicalfunc-
tions of two Boolean variables. The mode control
input M selects logical (M = High) orarithmetic (M =
Low) operation. The four select inputs (S0, S1, S2,
and S3)select thedesired logical orarithmetic func-
tions,whichinclude AND,OR,NAND,NOR,andex-
clusive-OR and-NOR in the logical mode, and
addition, subtraction, decrement, left-shift and
straighttransfer inthe arithmetic mode,according to
the truth table. The
HCC/HCF40181B
operation
may be interpreted with either active-low or active-
highdata atthe AandBwordinputsandthefunction
outputs F, by using the appropriate truth table. The
HCC/HCF40181B
contains logicfor full look-ahead
carry operation for fast carry generation using the
carry-generate and carry-propagate outputs G and
