54ACT251 - 8-Input Multiplexer

Download the 54ACT251 datasheet PDF. This datasheet also covers the 54AC251 variant, as both devices belong to the same 8-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

The 'AC/'ACT251 is a high-speed 8-input digital multiplexer.

It provides, in one package, the ability to select one bit of data from up to eight sources.

It can be used as universal function generator to generate any logic function of four variables.
