DESCRIPTION
The ACT157 is an high-speed CMOS QUAD
2-CHANNEL
MULTIPLEXER
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power
applications
maintaining
operation similar to equivalent Bipolar Schottky
TTL.
It consists of four 2-input digital multiplexers with
fabricated
with
high
speed
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
decoding determines whether the A or B inputs
get routed to theircorrespondingY outputs.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltagelevels.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
