Abstract
An electronic circuit arrangement is disclosed for converting an input voltage signal having a first voltage level into an output signal having a second voltage level. An input unit is provided for inputting the input voltage signal at the first voltage level, while an output unit is arranged for outputting the output signal at the output of the electronic circuit arrangement. A threshold value comparison unit serves for comparing the first voltage level of the input signal with a switch-on threshold value. The circuit arrangement furthermore contains an input impedance changeover unit for changing over an input impedance of the circuit arrangement from a low value to a high value after a predetermined delay duration after the first voltage level of the input voltage signal exceeded the switch-on threshold value.
