9-Bit Parity Generator/Checker

The TC74AC280 is an advanced high speed CMOS 9-BIT PARITY GENERATOR fabricated with silicon gate and double-layer metal wiring C2MOS technology.

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

Features

? High speed: tpd = 7.8 ns (typ.) at VCC = 5 V

? Low power dissipation: ICC = 8 μA (max) at Ta = 25°C

? High noise immunity: VNIH = VNIL = 28 VCC (min)

? Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines.

? Balanced propagation delays: tpLH ～ ? tpHL

? Wide operating voltage range: VCC (opr) = 2~5.5 V

? Pin and function compatible with 74F280
