In accordance with one the present disclosure, systems and methods are disclosed that include transmitting a binary signal from a signal source into a switch where the switch is in series between the signal source and a first circuit element. In addition, the switch is operating substantially in a switched mode and creates a switched output signal and the switch is controlled by the binary signal. Also disclosed in this method is detecting a negative voltage in a signal from a second circuit element. In this method the first circuit element is in series between the second circuit element and the switch, and upon detecting the negative voltage from the second circuit element the first circuit element creates high impedance in the first circuit element.
