74HC74AF
Features
- High speed: fmax = 77 MHz (typ.) at VCC = 5 V
- Low power dissipation: ICC = 2 μA (max) at Ta = 25°C
- High noise immunity: VNIH = VNIL = 28% VCC (min)
- Output drive capability: 10 LSTTL loads
- Symmetrical output impedance: |IOH| = IOL = 4 m A (min)
- Balanced propagation delays: tp LH ∼- tp HL
- Wide operating voltage range: VCC (opr) = 2~6 V
- Pin and function patible with 74LS74
