Abstract

A data transceiver device for bus communication includes: first and second semiconductor areas; a galvanic isolation means to galvanically isolate the first and second semiconductor areas; an input for receiving a signal to be transferred from the first semiconductor area to the second semiconductor area; a first capacitor in a first signal path and a second capacitor in a second signal path, each capacitor having a first plate connected to the first semiconductor area and a second plate connected to the second semiconductor area and each arranged for transferring a version of the received signal via the first and second signal paths, respectively; storage means having memory states controllable by the versions of the received signal and arranged to derive from the versions of the received signal the memory states. The storage means is arranged to obtain from the memory states an output signal in according to the received signal.
