TC74ACT164FT
Features
- High speed: fmax = 200 MHz (typ.) at VCC = 5 V
- Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
- patible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (max)
- Symmetrical output impedance: |IOH| = IOL = 24 m A (min)
Capability of driving 50 Ω tansmission lines.
- Balanced propagation delays: tp LH ≈ tp HL
- Pin and function patible with 74F164
