TEXAS INSTRUMENTS CD54/74AC280 CD54/74ACT280 9-Bit Odd/Even Parity Generator/Checker handbook(1)
The CD54/74AC280 and CD54/74ACT280 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 when an even number of data inputs is HIGH, while odd parity is indicated when an odd number of data inputs is HIGH.

Questions answered in these manuals
What is the function of the CD54/74AC280?
It is a 9-bit odd/even parity generator/checker that utilizes Advanced CMOS Logic technology.
From: TEXAS INSTRUMENTS CD54/74AC280 CD54/74ACT280 9-Bit Odd/Even Parity Generator/Checker handbook(1)
How is even parity indicated?
Even parity is indicated when the CE output is HIGH, which occurs when an even number of data inputs is HIGH.
From: TEXAS INSTRUMENTS CD54/74AC280 CD54/74ACT280 9-Bit Odd/Even Parity Generator/Checker handbook(1)
What is the typical propagation delay?
The typical propagation delay is 10ns at Voc = 5V, Ta = 25°C, and CL = 50pF.
From: TEXAS INSTRUMENTS CD54/74AC280 CD54/74ACT280 9-Bit Odd/Even Parity Generator/Checker handbook
Can this device check parity for words larger than nine bits?
Yes, by tying the YE output to any input of an additional AC280 or ACT280 parity checker.
