Features  
Description  
• Typical Propagation Delay = 17ns at V  
o
= 5V,  
The ’HC280 and ’HCT280 are 9-bit odd/even parity, generator  
checker devices. Both even and odd parity outputs are  
available for checking or generating parity for words up to nine  
bits long. Even parity is indicated (ΣE output is high) when an  
even number of data inputs is high. Odd parity is indicated  
(ΣO output is high) when an odd number of data inputs is  
high. Parity checking for words larger than 9 bits can be  
accomplished by tying the ΣE output to any input of an  
additional HC/HCT280 parity checker.
