A circuit arrangement (1) serves for driving a load, in particular a gate of a power transistor (M1). The circuit arrangement comprises a first input terminal (IN1) for inputting a voltage signal (Vin) in order to switch between states of the load, a first and a second output terminal (OUT1, OUT2) for outputting a first and second output voltage (Vout1, Vout2), a PNP bipolar transistor (Q1) and an NPN bipolar transistor (Q2), a first signal path (SP1) which is connected between the first input terminal and the base of the PNP bipolar transistor, and a second signal path (SP2) which is connected between the first input terminal and the base of the NPN bipolar transistor. The emitter of the first transistor is connected to a supply terminal (VCC). The collector of the first transistor is connected to the first output terminal. The emitter of the second transistor is connected to a ground terminal (GND). The collector of the second transistor is connected to the second output terminal. The first signal path contains a level shifter (Q6, R6) which is configured to shift the voltage signal into a level range suitable for switching the first transistor. The first signal path furthermore contains a first capacitor (C3), one end of which is connected upstream of the level shifter in the signal flow direction to the first signal path and the other end of which is connected downstream of the level shifter in the signal flow direction to the first signal path.
