DESCRIPTION
The 74AC158 is an advanced high-speed CMOS
QUAD
2-CHANNEL
MULTIPLEXER
(INVERTING) 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 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.
