A semiconductor circuit is provided in which no error signal is generated even when the circuit is exposed to a transient voltage noise that occurs with a transition from a first state indicating a conduction of a high-potential side switching device to a second state indicating a non-conduction of the high potential side switching device, or vice versa. A high potential switching device drive circuit 1 includes short circuit devices 31 and 32 that are controlled by the second level shifted signals S6 and S7 simultaneously generated across the second load resistances 30 and 29, respectively, to thereby serving to prevent a signal from being generated at one of the output sections where the other one of the first level shifted signals S4 and S5 is to be generated, when either one of the first shifted signals S4 and S5 in level shift circuit ON and OFF sections is generated across first load resistance 28 or 27 in a level shift circuit 2. |
