Abstract
A three input Exclusive OR-NOR gate circuit. The circuit comprises inverters for receiving three input signals and for providing three inverted input signals, a power potential terminal, a reference potential terminal, and an Exclusive NOR output node and an Exclusive OR output node. The circuit also includes transistors of a first conductivity type responsive to the signals on the output nodes for connecting the power potential terminal solely to one of the output nodes, and transistors of a second conductivity type responsive to the input and inverted input signals for connecting the reference potential terminal solely to the other of the output nodes.
