DESCRIPTION
The M74HCT157 is an high speed CMOS QUAD
2
CHANNEL MULTIPLEXER fabricated with
silicon gate C2MOS technology.
This device consists
of four 2-input digital
multiplexer with common select and strobe inputs.
When the STROBE(ST) input is held high,
selection of data is inhibited and all the outputs
become low. The SELECT decoding determines
whether the A or B inputs get routed to their
corresponding Y outputs.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
