QUAD 2-INPUT MULTIPLEXER
QUAD 2-INPUT MULTIPLEXERThe LSTTL/MSI SN54/74LS157 is a high speed Quad 2-Input Multiplexer.
Four bits of data from two sources can be selected using the common Select
and Enable inputs. The four buffered outputs present the selected data in the
true (non-inverted) form. The LS157 can also be used to generate any four
of the 16 different functions of two variables. The LS157 is fabricated with the
Schottky barrier diode process for high speed and is completely compatible
with all Motorola TTL families. Schottky Process for High Speed Multifunction Capability Non-Inverting Outputs Input Clamp Diodes Limit High Speed Termination Effects Special Circuitry Ensures Glitch Free Multiplexing ESD > 3500 Volts
