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 common Select and Enable inputs. The four outputs present the

selected data in the true (noninverted) form.

The MC74AC157/74ACT157 can also be used as a function

generator.
