SN54/74LS158

QUAD 2-INPUT MULTIPLEXER

The LSTTL/MSI SN54L/74LS158 is a high speed Quad 2-input Multiplex-

er. 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 LS158 is fabricated with the Schottky barrier

diode process for high speed and is completely compatible with all Motorola

TTL families.
