Functional Description

• Octal D-Type Flip Flop with 3-State Outputs

General

The 74HC574D is a high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate

C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

These 8-bit D-type flip-flops are controlled by a clock input (CK) and an output enable input (OE).

When the OE input is high, the eight outputs are in a high impedance state.

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

Features

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

(2) High speed: fMAX = 59 MHz (typ.) at VCC = 6.0 V

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

(4) Balanced propagation delays: tPLH » tPHL

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