The CD54HC354, CD74HC354, and CD74HCT354 are data
selectors/multiplexers that select one of eight sources. In both
types, the data select bits S0, S1 and S2 are stored in
transparent latches that are enabled by a low latch enable
input, LE.
In the HC/HCT354 the data enable input, E, controls
transparent latches that pass data to the outputs when E is
high and latches in new data when E is low.
In both types the three-state outputs are controlled by three
output-enable inputs OE1, OE2, and OE3.
