74VHC157 Quad 2-Input Multiplexer
General Description
The VHC157 is an advanced high speed CMOS Quad 2Channel Multiplexer fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation.
It consists of four 2-input digital multiplexers with common select and enable inputs.
When the ENABLE input is held “H” level, selection of data is inhibited and all the outputs become “L” level.
The SELECT decoding determines whether the I0x or I1x inputs get routed to their corresponding outputs.
