The MC74AC251/74ACT251 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 a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided.
This document is a technical datasheet for the MC74AC251 and MC74ACT251 devices. These are high-speed 8-input digital multiplexers that provide both true and complementary 3-state outputs. The device functions as an on-chip switch controlled by three select inputs and allows for universal function generation of four variables.
