MC74VHCT157A Quad 2-Channel Multiplexer The MC74VHCT157A is an advanced high speed CMOS quad 2 channel multiplexer fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
It consists of four 2 input digital multiplexers with common select (S) and enable (E) inputs.
When E is held High, selection of data is inhibited and all the outputs go Low.
The select decoding deter
