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.

Note 1: 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.
