TC74HC21AF Datasheet Dual 4-input And Gate

Manufacturer: Toshiba

Overview: TC74HC21AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC21AP, TC74HC21AF Dual 4-Input AND Gate The TC74HC21A is a high speed CMOS 4-INPUT AND GATE fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 4 stages including buffer an output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • High speed: tpd = 10 ns (typ. ) at VCC = 5 V.
  • Low power dissipation: ICC = 1 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 mA (min).
  • Balanced propagation delays: tpLH ∼.
  • tpHL.
  • Wide operating voltage range: VCC (opr) = 2 to 6 V.
  • Pin and function compatible with 74LS21 Pin Assignment TC74HC21AP TC74HC21AF.
