54F 74F280
9-Bit Parity Generator Checker
General Description
The ’F280 is a high-speed parity generator checker that ac-
cepts 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
