HD74HCT563/HD74HCT573
Octal Transparent Latches (with 3-state outputs)
Description
When the latch enable (LE) input is high, the Q outputs of HD74HCT563 will follow the inversion of the D
inputs and the Q outputs of HD74HCT573 will follow the D inputs.
When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enabled
returns high again. When a high logic level is applied to the output control input, all outputs go to a high
impedance state, regardless of what signals are present at the other inputs and the state of the storage
elements.
