9-Bit Odd/Even Parity Generator/Checker - CD74AC280
Datasheet
 

Description

The ’AC280 and ’ACT280 are 9-bit odd/even parity generator/checkers that utilize Advanced CMOS Logic technology. Both even and odd parity outputs are available for checking or generating parity for words up to nine bits long. Even parity is indicated (E output to any input of an additional ’AC280, ’ACT280 parity checker.
