74F381

4-Bit Arithmetic Logic Unit

General Description

Features

The 74F381 performs three arithmetic and three logic oper-

ations on two 4-bit words, A and B. Two additional select

input codes force the function outputs LOW or HIGH. Carry

propagate and generate outputs are provided for use with

the 74F182 carry lookahead generator for high-speed

expansion to longer word lengths. For ripple expansion,

refer to the 74F382 ALU data sheet.

■ Low input loading minimizes drive requirements

■ Performs six arithmetic and logic functions

■ Selectable LOW (clear) and HIGH (preset) functions

■ Carry generate and propagate outputs for use with carry

lookahead generator
