Abstract: A bus station and a bus system in which two bus stations are connected by at least one bus conductor. Messages are transmitted via a current flowing over the bus conductor. The bus station is supplied with operating current over the bus conductor. For this purpose, an energy storage device stores operating energy. In order to transmit messages, the bus station closes the switch and thus generates a current flow, which discharges the energy storage device of the bus station via the switch and resistor. The station transmits messages by causing the current to flow in the opposite direction by closing the switch. In order to prevent the energy storage device from discharging, the switch is opened.

Abstract: A receiving comparator for a data-transmission system comprising at least one control unit and data-transmission lines, in particular for at least one Controller Area Network (CAN) controller and one CAN bus system having a CAN bus (CB) is proposed, which is distinguished by the feature that the individual circuit elements are monolithically integrated. By generating a switching threshold which is independent of the operating voltage and temperature with the aid of a current source (I.sub.S), one prevents the CAN bus potentials from being asymmetrically influenced. The arrangement guarantees a processing of digital signals with a high data rate, whereby the input common-mode range extends up to above the supply voltage and to below ground.

Abstract: A transmitter end stage for a data transmission system comprising at least one control unit and data transmission lines, especially for a CAN bus system having at least one CAN controller and one CAN bus (CB) is proposed, characterized by the fact that the individual circuit elements of transmitter end stage 18 are integrated monolithically. As a result of the special layout and its circuit-design arrangement of the individual elements (3, 5; R1, D1, T1; R2, D2, T2; D10, D20) of the transmitter end stage, the effects of malfunctions, for example of short circuits of the data lines to ground or to the supply voltages, are reduced to a minimum. As a result of the special choice of pre-drivers (3, 5), minimum delay times are achieved, so that signals can be transmitted at a higher data rate.
