9-bit Odd/Even Parity Generators/Checkers

This parity generator/checker offers the designer a trade-off between reduce power consumption and high performance. Although the HD74LS280 is implemented without expander inputs, the corresponding function is provided by the availability of an input at pin 4 and the absence of any internal connection at pin 3.
