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 TC7MH157FK 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 (ST) is held “H” level, selection of data is
