Description  
Functional Diagram

The CD54AC280/3A and CD54ACT280/3A are 9-bit odd/  
even parity generator/checkers that utilize the Harris  
Advanced CMOS Logic technology. Both even and odd par-  
ity outputs are available for checking or generating parity  
words up to nine bits long. Even parity is indicated (E out-  
put is HIGH) when an even number of 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 output of an additional AC/ACT280 parity  
checker.
