Quad 2-Channel Multiplexer
The TC74VHC157 is an advanced high speed CMOS QUAD
2-CHANNEL MULTIPLEXER fabricated with silicon gate
C
2
MOS 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 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.
