74AC151 • 74ACT151 8-Input Multiplexer

November 1988 Revised November 1999

General Description

The AC/ACT151 is a high-speed 8-input digi t al multiplexer. It provides, in one package, the ability to select o ne line of data from up to eight sources. The AC/ACT151 can be used as a universal function generator to generate any logic function of four variable s. Both true and compl ementary outputs are provided.

Features

■ ICC reduced by 50%

■ Outputs source/sink 24 mA

■ ACT151 has TTL-compatible inputs
