A circuit in which driver units are associated with data networks that are coupled through at least two single transmission channels is provided. The driver units have a logical signal input and a logical signal output on their sides facing away from the data network, with the signal input or signal output of one driver unit being connected with the signal output or signal input of the other driver unit through a signal transmission channel in each case for coupling each of two data networks. A logical coupling control unit is looped into the coupling signal transmission channels. The unit blocks the signal path to the other signal transmission channel when predetermined blocking signal information appears on one signal transmission channel. This ensures that feedback and oscillation effects are suppressed during the transmission of signals over the transmission channels. The circuit can be used for coupling CAN data networks in motor vehicles.
