They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT354 data selectors/multiplexers contain full on-chip binary decoding, to select one-of-eight data sources. The data select address is stored in transparent latches that are enabled by a LOW on the latch enable input (LE). The transparent 8-bit data latches are enabled when the active LOW data enable input (E) is LOW. When the output enable input OE1 = HIGH, OE2 = HIGH or OE3 = LOW, the outputs go to the high impedance OFF-state. Operation of these output enable inputs does not affect the state of the latches.
