The MC10H160 is a 12-bit parity generator-checker. The output goes high when an odd number of inputs are high providing the odd parity function. Unconnected inputs are pulled to a logic low allowing parity detection and generation for less than 12-bits. The MC10H160 is a functional pin duplication of the standard 10K family part with 100% improvement in propagation delay and no increase in power-supply current.
