CD74HCT280 (ACTIVE) High Speed CMOS Logic 9-Bit Odd/Even Parity Generator/Checker

High Speed CMOS Logic 9-Bit Odd/Even Parity Generator/Checker - CD74HCT280
Datasheet
 

Description

The ’HC280 and ’HCT280 are 9-bit odd/even parity, generator checker devices. 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 HC/HCT280 parity checker.
