HD74HC563, HD74HC573
Octal Transparent Latches (with 3-state outputs)

Description
When the latch enable (LE) input is high, the Q outputs of HD74HC563 will follow the inversion of the D inputs and
the Q outputs of HD74HC573 will follow the D inputs. When the latch enable goes low, data at the D inputs will be
retained at the outputs until latch enable 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.
