Quad 2-Channel Multiplexer

2-CHANNEL MULTIPLEXER fabricated with silicon gate

Bipolar Schottky TTL while maintaining the CMOS low power

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and on

two supply systems such as battery back up. This circuit

prevents device destruction due to mismatched supply and input

voltages.

Features

•

The TC74VHC157 is an advanced high speed CMOS QUAD

It achieves the high speed operation similar to equivalent

It consists of four 2-input digital multiplexers with common

When the STROBE input is held “H” level, selection of data

The SELECT decoding determines whether the A or B inputs

An Input protection circuit ensures that 0 to 5.5 V can be
