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. Ordering Information PART NUMBER CD54HC354F3A CD74HC354E CD74HCT354E TEMP.
