TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC7MH157FK

Quad 2-Channel Multiplexer

The TC7MH157FK is an advanced high speed CMOS quad

technology.

It achieves the high speed operation similar to equivalent

bipolar schottky TTL while maintaining the CMOS low power

dissipation.

It consists of four 2-input digital multiplexers with common

select and strobe inputs.

When the strobe input (ST) is held “H” level, selection of data is

inhibited and all the outputs become “L” level.

The SELECT decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

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

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

• Power down protection is provided on all inputs.

• Pin and function compatible with 74ALS157
