Abstract
An interface circuit includes an input terminal, a controlled current sink, a current measurement arrangement, and a logic circuit. The input terminal is configured to receive an input signal. The controlled current sink is operably coupled to the input terminal, and is operable to controllably take up a current from the input terminal according to a transmission signal. The current measurement arrangement is configured to generate a current measurement signal based on the current taken up by the current sink. The logic circuit is operably coupled to receive the current measurement signal and the input signal, and is configured to generate a signal depending on the input signal.
