A driver circuit (18) generates a circuit output signal (VDO) which is provided to an electrical conductor (12) that furnishes a conductor output signal (VBO) to a load (14). The circuit and conductor output signals make corresponding circuit and conductor output transitions approximately between a pair of output voltage levels (VSS and VDD) between which there is an intermediate voltage level (VHH). Inductance (LB) and capacitance (CB and CL) of the conductor and load produce resonance that enables the conductor output signal to largely complete each conductor output transition while the circuit output signal is being held at or close to the intermediate voltage level for a short period. The circuit output signal rapidly completes each circuit output transition after the intermediate-level holding period is over. By operating in this manner, energy is re-used in a resonant manner, thereby substantially reducing power consumption.
