Abstract
A device for connecting to a two-wire communications bus, a bus station that, while utilizing the device, is able to send messages, represented on the bus lines as dominant and recessive bus levels, to additional connected bus stations and receive same from them. The device includes (a) an arrangement setting a dominant bus level in the form of a first voltage difference between the two bus lines by driving a first electric current, and the device is suitable for the recessive bus level to set in as the second voltage difference between the two bus lines, at least partially by the flowing of a discharge current via terminating resistors connected to the bus lines; and (b) an arrangement to speed up the setting of at least one of the bus levels by driving at least one additional electric current, at least in response to the presence of a switching condition.
