Datasheet Summary
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 mon 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 determines whether the A or B inputs get routed to the corresponding Y outputs.
The VHCT inputs are patible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V because it has...
