摘要:
A two-wire bus system for connecting a plurality of users has at least one damping circuit for damping line resonances in the two-wire bus system with respect to a reference potential. The damping characteristic of the damping circuit is selected such that the damping only becomes operative above a preestablished reference voltage threshold1 value. In this manner, it is achieved that a useful signal is not weakened by the damping circuit, but rather resonance voltages are damped only above the threshold value. It is advantageous if each of the users of the bus system has assigned to it a damping circuit.

An integrated semiconductor device having a thyristor includes outer npn-transistors, outer pnp-transistors, and an inner npn-transistor. The outer pnp-transistors and the inner npn-transistor are interconnected so as to form a thyristor to allow the inner transistor to be biased into conduction. Furthermore, a current flow takes place via the outer npn-transistors and the inner npn-transistor. The integrated semiconductor device having a thyristor minimizes interference produced in neighboring components.

The present invention provides a method and a device for serial transmission of data between a processor module and at least one peripheral element with the aid of a timing signal, a data signal and a selection signal. To reduce the number of lines necessary for the serial data transmission between the processor module and the at least one peripheral element at high data rate, the timing signal may be transmitted via two timing lines between the processor module and the at least one peripheral element, the data signal may be transmitted via two data lines between the processor module and the at least one peripheral element, and the selection signal may be transmitted via the data lines.
摘要:
A method for serially transmitting data between a first and a second station is provided, the first station unidirectionally transmitting at least two signals to the second station on two signal paths. In this method, a shift register is provided in each station, the two signal paths of the first station being routed in parallel into a shift register, and the data transmission to the second station being carried out by automatically clocking the shift register from a time base.
