9-Bit Parity Generator/Checker

The TC74ACT280 is an advanced high speed CMOS 9-BIT

PARITY GENERATOR fabricated with silicon gate and

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 compatible

with TTL, NMOS and CMOS output voltage levels.

The TC74ACT280 is composed 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.
