C2MOS technology. The IC generates either odd or even parity making It is composed of nine data inputs (A to I) and odd/ it flexible application. The word-length capability is even parity outputs (ODD and EVEN). The nine easily expanded by cascading. data inputs control the output conditions. When All inputs are equipped with protection circuits the number of high level input is odd, ODD against static discharge and transient excess output is kept high and EVEN output low. voltage.
