It is composed of nine data inputs (A to I) and odd/ even parity outputs ( ΣODD and ΣEVEN). The nine data inputs control the output conditions. When the number of high level input is odd, ΣODD output is kept high and ΣEVEN output low. Conversely, when the output is even, ΣEVEN output is kept high and ΣODD low. The IC generates either odd or even parity making it flexible application. The word-length capability is easily expanded by cascading. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
