74VHCT574A, Octal D-Type Flip-Flop

The 74VHCT574A 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).
