Abstract

A method and a device for bi-directional transmission of data are provided such that an interface for digital communication on a signal line is obtained which is suited for automotive use. In accordance with the present invention, the following are provided: at least one switchable load unit, the load unit of the temporary transmitter being able to be deenergized prior to transmission of the data; and being able to be reenergized after transmission of the data; in each case at least one switchable current-source unit is assigned to the load unit, the current-source unit of the transmitter being able to be clocked to generate the signals to be transmitted via the communication path; and in each case at least one comparator unit is assigned to the load unit, corresponding output signals being generated at the comparator unit of the receiver from the signals transmitted via the communication path.
