9-Bit Odd/Even Parity Generator/Checker

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 accom-

plished by tying the ∑E output to any input of an additional

’AC280, ’ACT280 parity checker.

Description

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 genera-

tor/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 par-

ity is indicated (∑E output is HIGH) when an even number of

2. Wafer and die for this part number is available which meets all elec-

trical specifications. Please contact your local TI sales office or cus-

tomer service for ordering information.
