The M74HC564 is an high speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS INVERTING fabricated with silicon gate C2MOS technology.
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 Qoutputs will be set to the logic state that were setup at the D inputs. 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 of M74HC564 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 voltage.
