74ACT157 - Quad 2-Input Multiplexer

Download the 74ACT157 datasheet PDF. This datasheet also covers the 74AC157 variant, as both devices belong to the same quad 2-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • s ICC and IOZ reduced by 50% s Outputs source/sink 24 mA s ACT157 has TTL-compatible inputs Ordering Code: Order Number Package Number Package.
