FAST AND LS TTL DATA
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.
