DESCRIPTION
The AC158 is an high-speed CMOS QUAD
2-CHANNEL MULTIPLEXER (INVERTING)
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology. It is
ideal for low 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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
