TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

9-Bit Parity Generator/Checker

The TC74HC280A is a high speed CMOS 9-BIT PARITY

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC280A 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.

Features

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 74LS280
