DESCRIPTION
The ACT158 is an high-speed CMOS QUAD
2-CHANNEL MULTIPLEXER fabricated with
sub-micron silicon gate and double-layer metal
wiring C
power applications maintaining high speed
operation similar to equivalent Bipolar Schottky
TTL.
It consists of four 2-input digital multiplexers with

common select and strobe inputs. It is an
inverting multiplexer. When the STROBE input is
held High selection of data is inhibit and all the
outputs become high. The SELECT decoding
determines whether the A or B inputs get routed
to their corresponding Y outputs.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
