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
