Dual D-Type Flip Flop with Preset and Clear

The TC74ACT74 is an advanced high speed CMOS D-FLIP

FLOP fabricated with silicon gate and double-layer metal wiring

C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

The signal level applied to the D INPUT is transferred to Q

OUTPUT during the positive going transition of the CK pulse.

CLR and PR are independent of the CK 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.

Features

• High speed: fmax = 180 MHz (typ.) at VCC = 5 V

• Low power dissipation: ICC = 4 µA (max) at Ta = 25°C

• Compatible with TTL outputs: VIL = 0.8 V (max)

VIH = 2.0 V (min)

• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)

Capability of driving 50

Ω

transmission lines.

• Balanced propagation delays: tpLH ∼− tpHL

• Pin and function compatible with 74F74
