A switching circuit apparatus driven by a relatively low DC power supply voltage, which includes a power supply terminal designed to receive a DC power source voltage, a pair of switching circuits comprising switching transistors (28, 30 and 32, 34) connected in parallel with each other and connected to the power supply terminal, first circuit means (10,12) connected for supplying the respective switching circuits with a switched signal, and a second circuit means (16, 18, 40, 14) connected for supplying the respective switching circuits with a pair of control signals which are opposite in phase and which are never both at a potential difference other than a prescribed potential at the same time. The switching circuit transistors (28, 30 or 32, 34) are all fully conductive prior to any transition in which two are rendered non-conductive by the control signals, thereby enable operation of the circuit with low power consumption. |
