A circuit includes a transformer, and primary and secondary circuits. The primary generates a first pulse across the primary coil of the transformer when a first input goes high and a second input goes low, and generates a second pulse when the first and second inputs go high. The primary generates a third pulse when the first and second inputs go low, and generates a fourth pulse when the first input goes low and the second input goes high. A first output from the secondary goes high when a pulse is induced across the secondary coil by the first or second pulse, and goes low when a pulse is induced by the third or fourth pulse. A second output from the secondary goes high when a pulse is induced by the second or fourth pulse, and goes low when a pulse is induced by the first or third pulse.
