SCHS250A 9-Bit Odd/Even Parity Generator/Checker August 1998 -Revised May 2000 Features 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. Buffered Inputs Typical Propagation Delay

1. When ordering, use the entire part number. Add the suffix 96 to
obtain the variant in the tape and reel. 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 …
