DESCRIPTION
HCF40181B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in SOP packages.
HCF40181B is a low-power 4-bit parallel
arithmetic logic unit (ALU) capable of providing 16
binary arithmetic operations on two 4-bit words

and 16 logical functions of two Boolean variables.
The mode control input M selects logical (M =
High) or arithmetic (M = Low) operations. The four
select inputs (S0, S1, S2, and S3) select the
desired logical or arithmetic functions, which
include AND, OR, NAND, NOR, and exclusive-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. HCF40181B operations 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.
HCF40181B contains logic for full look-ahead
carry operations for fast carry generations using
the carry-generate and carry propagate outputs G
