2-Channel Multiplexer
The TC7WH157 is an advanced high speed CMOS 2-Channel
Multiplexer fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation. It consists of 2-input digital multiplexer with
common select and strobe inputs.
When the STROBE input 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 7 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 two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
