74AC280 9-Bit Parity Generator/Checker
November 1988
Revised November 1999
74AC280
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 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 out-
put.
