摘要： A data bus system including a serial data bus operated with complementary logic signals, several system users, communicating with each other via the bus lines of the data bus, and several output stages complete with a transmitter and a receiver, where each system user is assigned an output stage for coupling to the data bus. The output stage of each system user features a terminating network, with the determining network of at least on output stage being low impedance, active, switching, and internally switchable, with the terminating network of at least one more output stage being passive and low impedance, and with the terminating networks of all other output stages being passive and high impedance.
