A circuit is disclosed. The circuit includes a transmitter having an input terminal arranged to receive input data and a transmission node arranged to transmit intermediate data corresponding to the input data, and a receiver having a receive node arranged to receive the intermediate data and an output terminal arranged to produce output data corresponding to the input data, the receiver further including a dV/dt detector circuit coupled to the receive node and arranged to stop the production of the output data at the output terminal when the dV/dt detector circuit detects a rate of change of voltage with respect to time greater than a predetermined threshold.
