DESCRIPTION
The M74HCT158 is an high speed CMOS QUAD
2 CHANNEL MULTIPLEXER fabricated with
silicon gate C²MOS technology.
This device consists of four 2-input digital
multiplexer with common select and strobe inputs.
The M74HCT158 is an inverting multiplexer.
When the STROBE(ST) input is held high,
selection of data is inhibited 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 are equipped with protection circuits
against static discharge and transient excess
voltage.
