This 8 bit D-TYPE FLIP FLOP is controlled by a clock input (CK) and an output enable input (OE). DILC-20 FPC-20 ORDER CODES PACKAGE FM EM DILC FPC M54HC574D M54HC574K M54HC574D1 M54HC574K1 On the positive transition of the clock, the Q outputs 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 OE is in 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 voltage.
