    摘要： 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.

    摘要： An output stage, especially a switching output stage for switching inductive loads, having a plurality of individual output stages that are connected in parallel, which include degenerative transistors, in the degenerative path of which one respective Zener diode is present. The electric power during a switching-off process can be distributed in a particularly uniform manner to the individual output stages or transistors by disposing the Zener diodes near the associated transistors so that they are thermally coupled to the respectively associated transistor and their Zener voltage increases with increasing temperature.
