SN54/74LS280  
9-BIT ODD/EVEN PARITY  
GENERATORS/CHECKERS  
The SN54/74LS280 is a Universal 9-Bit Parity Generator/Checker. It fea-  
tures odd/even outputs to facilitate either odd or even parity. By cascading,  
the word length is easily expanded.  
The LS280 is designed without the expander input implementation, but the  
correspondingfunction is provided by an input at Pin 4 and the absence of any  
connection at Pin 3. This design permits the LS280 to be substituted for the  
LS180 which results in improved performance. The LS280 has buffered  
inputs to lower the drive requirements to one LS unit load.
