TOSHIBA TC74VHC00FK(EL,K)

The TC74VHC00 is an advanced high speed CMOS 2-INPUT NAND GATE fabricated with silicon gate C²MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

• High speed: tpd = 3.7 ns (typ.) at VCC = 5 V
• Low power dissipation: Icc = 2 μA (max) at Ta = 25 °C
• High noise immunity: ΔVNIH = VNIL = 28% VCC (min)
• Power down protection is provided on all inputs.
• Balanced propagation delays: tpLH ≃ tpHL
• Wide operating voltage range: VCC(opr) = 2 to 5.5 V
• Low noise: VOLP = 0.8 V (max)
• Pin and function compatible with 74ALS00
