SN74LS157
Quad 2−Input Multiplexer
The LSTTL/MSI SN74LS157 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
ON Semiconductor 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
