Overview

TC74HC85AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC85AP, TC74HC85AF 4-Bit Magnitude Comparator The TC74HC85A is a high speed CMOS 4 BIT MAGNITUDE COMPARATOR fabricated with silicon gate C2MOS technology.

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

The TC74HC85A compares tow 4-bit words applied to inputs A0-A3 and B0-B3, and provides a high voltage level on one of three outputs: A > B, A < B, or A = B.

Key Features

  • High speed: tpd = 22 ns (typ. ) at VCC = 5 V.
  • Low power dissipation: ICC = 4 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 74LS85 Pin Assignment TC74HC85AP TC74HC85AF.
