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.
