74F382 - 4-Bit Arithmetic Logic

General Description

The 74F382 performs three arithmetic and three logic operations on two 4-bit words, A and B.

Two additional Select input codes force the Function outputs LOW or HIGH.

An Overflow output is provided for convenience in twos complement arithmetic.

Key Features

  • s Performs six arithmetic and logic functions s Selectable LOW (clear) and HIGH (preset) functions s LOW input loading minimizes drive requirements s Carry output for ripple expansion s Overflow output for twos complement arithmetic Ordering Code: Order Number 74F382SC 74F382SJ 74F382PC Package Number M20B M20D N20A Package.
