Abstract
The invention relates to an interfacing device for transmission through interconnections used for sending a plurality of electrical signals. The interfacing device of the invention comprises signal terminals and a common terminal. A transmitting circuit receives the input signals of the transmitting circuit coming from a source. The output of the transmitting circuit delivers, when the transmitting circuit is in the activated state, voltages between one of the signal terminals and the reference terminal (ground). A receiving circuit delivers, when the receiving circuit is in the activated state, output signals of the receiving circuit determined each by the voltage between one of the signal terminals and the common terminal, to the destination. In the closed state, the common terminal switching circuit is, for the common terminal, equivalent to a voltage source delivering a constant voltage, connected in series with a passive two-terminal circuit element presenting a low impedance.
