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.

• Outputs Source/Sink 24 mA

• ′ACT157 Has TTL Compatible Inputs
