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.

MARKING

The select decoding determines whether the A or B inputs get routed

to the corresponding Y outputs.

DIAGRAMS

The VHCT inputs are compatible with TTL levels. This device can

be used as a level converter for interfacing 3.3 V to 5.0 V because it

has full 5.0 V CMOS level output swings.

The VHCT157A input structures provide protection when voltages

between 0 V and 5.5 V are applied, regardless of the supply voltage.

The output structures also provide protection when V = 0 V. These

input and output structures help prevent device destruction caused by

supply voltage−input/output voltage mismatch, battery backup, hot

insertion, etc.

The inputs tolerate voltages up to 7.0 V, allowing the interface of

5.0 V systems to 3.0 V systems.
