MC74F158A QUAD 2-INPUT MULTIPLEXER
The MC74F158A 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 F158A can also generate any four of the 16 different functions of two variables.
