HD74ACT280 Datasheet 9-bit Parity Generator/checker

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74AC280/HD74ACT280 9-bit Parity Generator/Checker.

General Description

The HD74AC280/HD74ACT280 is a high-speed parity generator/checker that accepts nine bits of input data and detects whether an even or an odd number of these inputs is High.

If an even number of inputs is High, the Sum Even output is High.

If an odd number is High, the Sum Even output is Low.
