For driving an IC module with output digital signals of another IC module, mutually-identical input circuits are provided for the individual digital signals, the respective switching thresholds of the input circuits, controlled by a control circuit shared by the input circuits, being set based on the DC component appearing in a digital signal representative of the remaining digital signals. Positional changes of the digital signals are therefore compensated by positional changes of the switching thresholds.
