A driver circuit is provided comprising at least two equal main units (MU) each comprising at least two sub units (SU) coupled to a data output (dout). Each sub unit (SU) is adapted to represent a respective predetermined impedance. Each main unit (MU) is adapted to that, when in a data mode, each sub unit (SU) of the respective main unit (MU) is switchable to either a first or second reference potential depending on a data signal to transmit. Each main unit (MU) is further adapted to that, when in a termination mode, the sub units (SU) of the respective main unit (MU) are switched to either the first or second reference potential such that an output of the respective main unit (MU) is neutral with respect to the driving of the data output (dout) to the first or second reference potential.
