74HCT280D, 74HC280, 9-bit odd/even parity generator/checker
The 74HC280; 74HCT280 is a 9-bit parity generator or checker.
Both even and odd parity outputs are available.
The even parity output (PE) is HIGH when an even number of data inputs (I0 to I8) is HIGH.
The odd parity output (PO) is HIGH when an odd number of data inputs are HIGH.
