Functional Description

• Dual D-Type Flip-Flop with Preset and Clear

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 L level.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

特性 Features

(1) Wide operating temperature range: Topr = -40 to 125 (Note 1)

(2) High speed: fMAX = 77 MHz (typ.) at VCC = 5 V

(3) Low power dissipation: ICC = 2.0 μA (max) at Ta = 25

(4) Balanced propagation delays: tPLH » tPHL

(5) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
