DESCRIPTION
The 74AC157 is an advanced high-speed CMOS
QUAD 2-CHANNEL MULTIPLEXER fabricated
with sub-micron silicon gate and double-layer
metal wiring C
2
MOS tecnology.
It consists of four 2-input digital multiplexer with
common SELECT and STROBE inputs. It is a
non-inverting multiplexer. When the STROBE
input is held high selection of data is inhibit 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 and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
