74HCT280 generator/checker equivalent, 9-bit odd/even parity generator/checker.
* Word-length easily expanded by cascading
* Generates either odd or even parity for nine data bits
* Wide supply voltage range from 2.0 to 6.0 V
* Input .
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 nu.
