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.

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
