MN54AC280-X REV 1B0
9 - Bit Parity Generator/Checker
General Description
The AC280 is a high-speed parity generator/checker that accepts nine bits of input data
and detects whether an even or 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.

Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specifications should be met, without exception, to ensure that
the system design is reliable over its power supply, temperature, output/input
loading variables. National does not recommend operation of FACT TM circuits outside
databook specifications.
