These device consist of four 2-input digital
multiplexer with common select and strobe inputs.
When the STROBE input is held high, selection of
data is inhibited and all the outputs become low.
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.
