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.
