74VHCT74A Datasheet (STMicroelectronics)

74VHCT74A, Dual D-Type Flip-Flop

The 74VHCT74A is an advanced high-speed CMOS DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

A signal on the D INPUT is transfered to the Q OUTPUT during the positive going transition of the clock pulse.
