74F181

4-Bit Arithmetic Logic Unit

General Description

Features

The 74F181 is a 4-bit Arithmetic logic Unit (ALU) which can

perform all the possible 16 logic operations on two vari-

ables and a variety of arithmetic operations. It is 40% faster

than the Schottky ALU and only consumes 30% as much

power.
