Quad 2Input Multiplexer
The MC74AC157/74ACT157 is a highspeed quad 2input
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.
