Abstract

A network interface is designed for two-wire reception via a serial bus and has a differential receiver which is connected to input lines. The network interface likewise has an element for recognizing error states on the bus lines. It is designed such that it changes into single-wire operation after recognizing the error state, in order to maintain the data traffic. In this case, one input line is connected to a fixed terminal potential. The terminal potential is in this case selected such that the magnitude of the potential difference between the two input lines is the same for both bit levels.
