74LS158

The 74LS158is 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 LS158 can also generate any four of the 16 different functions of two variables. The 74LS158 is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families.
