9-Bit Parity Generator/Checker

General Description

Features

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.

■ I_CCreduced by 50%

■ 9-bit width for memory applications

■ AC280: 5962-92201
