ABSTRACT:
A driving circuit includes: a first semiconductor switch with its source connected to a high-voltage power source; amultiple number of diodes with their anodes commonly connected to the drain of the first semiconductor switch; a multiple number of second semiconductor switches, each being connected at the drain to the cathode of the corresponding diode and the sources being commonly connected to a low-voltage power source. In this configuration, the first semiconductor switch is turned on so that all the outputs once have the high voltage supplied and then the plural second semiconductor switches are selectively turned on so as to output the low voltage from their output terminals.
