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 (T 1 , T 2 ; T 4 , T 5 ). The buffer is arranged in a second supply voltage domain (VDD 1 , GND 1 ). Furthermore, a control circuit is coupled to the buffer for controlling the first and second switch (T 1 , T 2 ; T 4 , T 5 ) such that during a transition of an input signal of the input/output circuit ( 10 ) both switches (T 1 , T 2 ; T 4 , T 5 ) are temporarily kept in a conducting state and a crowbar current flows through the buffer (INV).
