Overview

TC74HC4078AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4078AP, TC74HC4078AF 8-Input OR/NOR Gate The TC74HC4078A is a high speed CMOS 8-INPUT NOR GATE fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

Output X is an 8-INPUT NOR, output Y is an 8-INPUT OR.

Key Features

  • High speed: tpd = 13 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 4078B Pin Assignment TC74HC4078AP TC74HC4078.
