CD74HCT280 - High Speed CMOS Logic 9-Bit Odd/Even Parity Generator/Checker
Updated : 2020-01-09 14:43:13Description
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.
