9-Bit Parity Generator/Checker
The TC74ACT280 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.
This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are patible with TTL, NMOS and CMOS output voltage levels.
The TC74ACT280 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. The even parity output is high when an even number of data inputs are high.
The word-length capability is easily expanded by cascading. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
- High speed: tpd = 9.2 ns (typ.) at VCC = 5 V
- Low power dissipation: ICC = 8 μA (max) at Ta = 25°C
- patible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
- Symmetrical output impedance: |IOH| = IOL = 24 m A (min)
Capability of driving 50 Ω transmission lines.
- Balanced propagation delays: tp LH ∼- tp HL
- Pin and function patible with 74F280
