TC74VHC21FT
Features
- High speed: tpd = 3.3 ns (typ.) at VCC = 5 V
- Low power dissipation: ICC = 2 μA (max) at Ta = 25°C
- High noise immunity: VNIH = VNIL = 28% VCC (min)
- Power down protection is provided on all inputs.
- Balanced propagation delays: tp LH ≈ tp HL
- Wide operating voltage range: VCC (opr) = 2 to 5.5 V
- Pin and function patible with 74ALS21
Note: xxx FN (JEDEC SOP) is not available in Japan.
