Functional Description

? Quad D-Type Flip-Flop with Clear

General

The 74HC175D is a high speed CMOS D-TYPE 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.

Information signals applied to D inputs are transferred to the Q and Q outputs on the positive going edge of the

clock pulse.

When the CLR input is held low, the Q outputs are at the low logic level and the Q outputs are at the high logic

level independent of the other inputs.

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

Features

(1) High speed: fMAX = 63 MHz (typ.) at VCC = 5 V

(2) Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 

(3) Balanced propagation delays: tPLH ≈ tPHL

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