QUAD 2-INPUT MULTIPLEXER
-The MC74AC158/74ACT158 is a high-speed quad 2-input multiplexer. It selects
four bits of data from two sources using the common Select and Enable inputs.
The four buffered outputs present the selected data in the inverted form. The
MC74AC158/74ACT158 can also be used as a function generator. Outputs Source/Sink 24 mA ′ACT158 Has TTL Compatible Inputs
