9-BIT PARITY GENERATOR/
CHECKER
nine bits of input data and detects whether an even or an odd number of these
inputs is HIGH. If an even number of inputs is HIGH, the Sum Even output is
HIGH. If an odd number is HIGH, the Sum Even output is LOW. The Sum Odd
output is the complement of the Sum Even output.
The MC54/74F280 is a high-speed parity generator/checker that accepts
