Abstract
In a semiconductor circuit device including a first terminal adapted to receive a first voltage and a second terminal adapted to receive a second voltage lower than the first voltage, a capacitive circuit and a short-circuit preventing circuit are provided in series between the first and second terminals. In this case, when the capacitive element is in an insulating (non-conductive) state, the short-circuit preventing circuit is in a conductive state, while, when the capacitive circuit is in a conductive state, the short-circuit preventing circuit is in an insulating state.
