An electronic circuit has a driver circuit to drive a signal onto a signal line. The driver circuit contains a first switching device with a first forward resistance between a first supply voltage terminal and the signal line, and a second switching device with a second forward resistance between a second supply voltage terminal and the signal line. A control circuit is provided to generate a first and a second control signal to control the first and second switching devices in a first operating mode such that, depending on the signal which is to be driven, either the first switching device or the second switching device is through-connected. In a second operating mode, the first switching device and the second switching device are essentially through-connected with the aid of the first and second control signals so that the first and second forward resistances together form a terminating resistance.
