The M74HCT564 is an high speed CMOS OCTAL
D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS
INVERTING fabricated with silicon gate C2MOS
This 8 bit D-TYPE FLIP FLOP is controlled by a
clock input (CK) and an output enable input (OE).
On the positive transition of the clock, the Q
outputs will be set to the logic state that were
setup at the D inputs complements.
While the OE input is at low level, the eight outputs
will be in a normal logic state (high or low logic
level) and while high level the outputs will be in a
high impedance state.
The output control does not affect the internal
operation of flip-flops; that is, the old data can be
retained or the new data can be entered even
while the outputs are off.
All inputs are equipped with protection circuits
against static discharge and transient excess
