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.

NOTES:
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
or generating parity for words up to nine bits long. Even parity is indicated (∑E output is HIGH) when an even number of
2. Wafer and die for this part number is available which meets all electrical specifications. Please contact your local TI sales office or customer service for ordering information.
