It has the same high speed performance of LSTTL combined with true CMOS low consumption. It is composed of nine data inputs (A to I) and odd/even parity outputs ( ODD and EVEN). The nine data inputs control the output conditions. When the number of high level inputs is odd, ODD output is kept high and EVEN output low. Conversely, when the number is even , EVEN output is kept high and ODD low. This 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.
