Manufacturer: onsemi

Overview: MC74AC157, MC74ACT157 Quad 2-Input Multiplexer The MC74AC157/74ACT157 is a high−speed quad 2−input multiplexer. Four bits of data from two sources can be selected using the mon Select and Enable inputs. The four outputs present the selected data in the true (non−inverted) form. The MC74AC157/74ACT157 can also be used as a function generator.

General Description

The MC74AC157/74ACT157 is a quad 2−input multiplexer.

It selects four bits of data from two sources under the control of a mon Select input (S).

The Enable input (E) is active−LOW.
