Octal D-Type Flip-Flop with 3-State Output

The TC74AC574 is an advanced high speed CMOS OCTAL 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.

Features

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

• Low power dissipation: ICC = 8 μA (max) at Ta = 25°C

• High noise immunity: VNIH = VNIL = 28 VCC (min)

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

Capability of driving 50 Ω

transmission lines

• Balanced propagation delays: tpLH ∼ − tpHL

• Wide operating voltage range: VCC (opr) = 2 to 5.5 V

• Pin and function compatible with 74F574
