DESCRIPTION
The AC157 is an high-speed CMOS QUAD
2-CHANNEL
MULTIPLEXER
sub-micron silicon gate and double-layer metal
wiring C

MOS technology. It is ideal for low
power
applications
maintaining
operation similar to equivalent Bipolar Schottky
TTL.
fabricated
with
high
speed
It consists of four 2-input digital multiplexers 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 theircorrespondingY outputs.
All
inputs and
outputs

them 2KV ESD immunity and transient excess
