74ACT74 Datasheet (STMicroelectronics)

74ACT74, Dual D-Type Flip-Flop

The 74ACT74 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 tecnology.

A signal on the D INPUT is transferred to the Q and Q OUTPUTS during the positive going transition of the clock pulse.
