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
