74AC157 • 74ACT157

Quad 2-Input Multiplexer

General Description

Features

The AC/ACT157 is a high-speed quad 2-input multiplexer.

Four bits of data from two sources can be selected using

the common Select and Enable inputs. The four outputs

present the selected data in the true (noninverted) form.

The AC/ACT157 can also be used as a function generator.

■ I_CCand I_OZreduced by 50%

■ Outputs source/sink 24 mA

■ ACT157 has TTL-compatible inputs
