9-bit Odd / Even Parity Generator / Checker

This parity generator / checker offers the designer a trade-off between reduced 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.
