Part Details:

54AC280 September 1998 54AC280 9-Bit 9-Bit Parity Generator/Checker Parity General Description Features The AC280 is a high-speed parity generator/checker that n I reduced by 50% CC accepts nine bits of input data and detects whether an even n 9-bit width for memory applications or an odd number of these inputs is HIGH. If an even number Generator/Checker n Standard Microcircuit Drawing (SMD) 5962-92201 of inputs is HIGH, the Sum Even output is HIGH. If an oddnumber is HIGH, the Sum Even output is LOW. The SumOdd output is the complement of the Sum Even output.
