Abstract
A switch control circuit includes a plurality of first voltage generation circuits that generate a plurality of second control signals by level-shifting a plurality of first control signals using a reference voltage. A plurality of cut-off circuits controlling whether or not to supply the reference voltage to a corresponding one of the plurality of first voltage generation circuits. A control circuit is configured to control the cut-off circuits in such a manner that the reference voltage supplied to at least one first voltage generation circuit is cut off to the other first voltage generation circuits after a state of the first control signal supplied to the at least one first generation circuit is changed. In some embodiments, the reference voltage to the other first generation circuits is cut-off for a predetermined time period.
