74HC74D CMOS Digital Integrated Circuits Silicon Monolithic 74HC74D 1. Functional Description Dual D-Type Flip-Flop with Preset and Clear 2. General The 74HC74D is a high speed CMOS D FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CLOCK pulse. CLEAR and PRESET are independent of the CLOCK and are accomplished by setting the appropriate input to an level. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3. Features (1) Wide operating temperature range: T = -40 to 125 (Note 1) opr (2) High speed: f = 77 MHz (typ.) at V = 5 V MAX CC (3) Low power dissipation: I = 2.0 A (max) at T = 25 CC a (4) Balanced propagation delays: t t PLH PHL (5) Wide operating voltage range: V = 2.0 to 6.0 V CC(opr) Note 1: Operating Range spec of T = -40 to 125 is applicable only for the products which manufactured after opr July 2020. 4.
