摘要

A device for the cut places moderate connect a first circuit, which a first supply voltage is used, and a second circuit comprising a second supply voltage is used, which differs from the first supply voltage, wherein the device has the following features:a driver circuit (300), which a driver network (300), the driver supply voltage terminals, with controllable switches (106, 108) are connected, wherein the controllable switch (106, 108) resistive elements or of resistive elements are defined;a receiver circuit (320), which has a reception network, which is a resistive element and the receiver supply voltage terminals; anda connecting line (130), which the driver circuit (300) and connects the receiving circuit, wherein the controllable switch (106, 108) have two switch configurations, wherein a first switch configuration in a high voltage on the connecting line (130) and a second switch configuration results in a low voltage on the connecting line (130) results, wherein the resistive elements in the driver network (300) and the receiver network (320) have values, so that a sum of the high voltage and the low voltage equal to the second supply voltage in a range of 10% about the second supply voltage is, when the first supply voltage is applied to the driver supply voltage terminals is applied, and when the second supply voltage is applied to the receiver is applied supply voltage terminals.
