The 74HC/HCT563 are octal D-type
transparent latches featuring
separate D-type inputs for each latch
and inverting 3-state outputs for bus
oriented applications.
A latch enable (LE) input and an
output enable (OE) input are common
to all latches.
The “563” is functionally identical to
the “573”, but has inverted outputs.
The “563” consists of eight D-type
transparent latches with 3-state
inverting outputs. The LE and OE are

common to all latches.
When LE is HIGH, data at the D
inputs enter the latches. In this
condition the latches are transparent,
i.e. a latch output will change state
each time its corresponding D-input
changes.
When LE is LOW the latches store the
information that was present at the
D-inputs a set-up time preceding the
HIGH-to-LOW transition of LE.
When OE is LOW, the contents of the
8 latches are available at the outputs.
When OE is HIGH, the outputs go to
the high impedance OFF-state.
Operation of the OE input does not
affect the state of the latches.
