General Description
The ’AC/’ACT151 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one 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 variables. Both true and complementary outputs are provided.

Functional Description
The ’AC/’ACT151 is a logic implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S1, S2. Both true and complementary outputs are provided. The Enable input (E) is active LOW. When it is not activated, the comp……
