TC74HC280AP 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 patible with 74LS280

TC74HC280AP Description

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC280A is posed of nine data inputs A thru I and odd/even parity outputs Σ ODD and Σ EVEN. The odd parity output is high when an odd number of data inputs are high.
