TC74AC139F
TC74AC139F is Dual 2-to-4 Line Decoder manufactured by Toshiba.
Features
- High speed: tpd = 5.9 ns (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 m A (min) Capability of driving 50 Ω transmission lines.
- Balanced propagation delays: tp LH ∼- tp HL
- Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
- Pin and function patible with 74F139
