Abstract
For the transmission of data in the form of difference signals between subscribers connected to a bus, bus couplers are provided which permit switching between transmit and receive operation. The bus couplers each include a multiplexer connected in such a manner that, for receive operation, only push-pull states of the difference signal are evaluated. If common-mode states occur, the immediately previously decoded data are used. In the case of interference, e.g. one subscriber experiences a short circuit, his bus is terminated passively so that the bus traffic for the other subscribers is not adversely affected.
