CD54AC280F3A

9位奇/偶校验发生器/校验器 9-Bit Odd/Even Parity Generator/Checker

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 is HIGH when an even number of data inputs is HIGH. Odd parity is indicated ∑O output is HIGH when an odd number of data inputs is HIGH. Parity checking for words larger than nine bits can be accomplished by tying the ∑E output to any input of an additional ’AC280, ’ACT280 parity checker.
