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.
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 MOS
tecnology.
It consists of four 2-input digital multiplexer with
common select and strobe inputs. It is an inverting
