Product specification
74F181
Arithmetic logic unit
1
March 3, 1989
853–0351 95947
FEATURES
Provides 16 arithmetic operation: add, subtract, compare, and
double; plus 12 other arithmetic operations
Provides all 16 logic operations of two variables: Exclusive-OR,
Compare, AND, NAND, NOR, OR, plus 10 other logic operations
Full look-ahead carry for high speed arithmetic operation on long
words
40% faster than ’S181 with only 30% ’S181 power consumption
Available in 300mil-wide Slim 24-pin Dual In-Line package
DESCRIPTION
The 74F181 is a 4-bit high-speed parallel Arithmetic Logic Unit
(ALU). Controlled by the four Function Select inputs (S0–S3) and
the Mode Control input (M), it can perform all the 16 possible logic
operations or 16 different arithmetic operations on active-High or
active-Low operands. The Function Table lists these operations.
