In a digital interface comprising a current limiter, a reference voltage proportional to the bus voltage is generated and the current limiter is switched on when the incoming digital signal is higher than the reference voltage and switched of when the incoming signal is smaller than the reference voltage. The "high/low-ratio" of the digital signal at the output of the interface is substantially improved by the use of the reference voltage.
