M74HC74 DUAL D-TYPE FLIP-FLOP

The M54/74HC74 is a high speed CMOS DUAL D TYPE FLOP WITH PRESET AND CLEAR fabri2 cated in silicon gate C MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. A signal on the D INPUT is transferred to the Q OUTPUT during the positive going tr.
