An inverse toggle circuit includes a pair of input connections for receiving each of four possible input signal combinations in a sequential rotational manner. Each of four data paths are defined to be exercised in accordance with a respective input signal combination. A first output connection is controlled by first and third data paths. A second output connection is controlled by second and fourth data paths. Each data path is defined such that a currently exercised data path generates an output signal having an asserted state on the output connection that is controlled by the currently exercised data path. The currently exercised data path is also defined to cause a next data path in the sequence to generate an output signal having a non-asserted state on the output connection that is controlled by the next data path.
