A driver boost signaling circuit provides a pulse boost to the first cycle of an output pulse wave applied to an associated load. The circuit includes a signal generator circuit generating a signal including a series of pulses, a determining circuit determining a high impedance state of a signal load line and a first one or more cycles of the series of pulses applied to the load line following the high impedance condition, and a receiving circuit receiving a control signal. A logic circuit generates first and second logical signals responsive to the control signal and to the determining circuit determining the first one or more cycles and other cycles of the series of pulses. A switchable impedance circuit coupling the signal generator with the associated load line is responsive to the first logical signal to provide a low impedance level between the signal generator circuit and the associated signal load line, and to the second logical signal to provide a high impedance level between the signal generator circuit and the associated signal load line.
