9-Bit Odd/Even Parity Generator/Checker
X74_280 parity generator/checker compares up to nine data inputs (I – A) and provides both even (EVEN) and odd parity (ODD) outputs. The EVEN output is High when an even number of inputs is High. The ODD output is High when an odd number of inputs is High.
Expansion to larger word sizes is accomplished by tying the ODD outputs of up to nine parallel components to the data inputs of one more X74_280; all other inputs are tied to ground.
