Abstract
An integrated circuit is disclosed having at least one digital input, which has a first circuit section that has a current-voltage characteristic and that in the absence of an input signal holds a voltage at the input at a defined value, and having a second circuit section that provides a signal that is internal to the circuit and whose state does not directly show itself at an output of the circuit. The first circuit section has a control input for a control signal and is designed to change its current-voltage characteristic when the control signal is present at the control input. In addition, a method for testing such a circuit is disclosed.
