An electronic device comprising at least one input/output circuit (10) in a first supply voltage domain (VDD, GND) is provided. The electronic device furthermore comprises a buffer (INV) which is coupled to the input/output circuit for driving an input of the input/output circuit (10). The buffer comprises a first and second switch (Tl, T2; T4, T5). The buffer is arranged in a second supply voltage domain (VDDl, GNDl). Furthermore, a control circuit is coupled to the buffer for controlling the first and second switch (Tl, T2; T4, T5) such that during a transition of an input signal of the input/output circuit (10) both switches (Tl, T2; T4, T5) are temporarily kept in a conducting state and a crowbar current flows through the buffer (INV). |
