Functional Diagram
June 1997
COMPLETE DATA SHEET COMING SOON! 9-Bit Odd/Even Parity Generator/Checker
Description
CD54HC280/3A CD54HCT280/3A 9-bit odd/ even parity, generator checker devices. Both even parity outputs available checking generating parity words 9-bits long. Even parity indicated output high) when even number data inputs high. parity indicated output high) when number data inputs high. Parity checking words larger than 9-bits accomplished tying output input additional CD54HC/HCT280 parity checker.
