The 74VHC574 is an advanced high-speed CMOS OCTAL D-TYPE FLIP FLOP with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring 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 Q outputs will be set to logic states that were setup
