    • A digital circuit is described which has an input for supplying an input signal through a switching element and an activation input by which it can be switched to an activated or deactivated state. The circuit also contains a first output supplying in a non-inverted manner in the activated state the level of the input signal immediately before switching the switching element to a non-conducting state and a second output supplying in an inverted manner the level of the input signal immediately before switching the switching element to the non-conducting state. In the deactivated state, it furnishes a first logical level to both outputs. The circuit also has a logical unit that is connected to both outputs on the input side and to a control connection of the switching element on the output side. The logical unit switches the switching element to a conductive state, when the first logical level is applied on both outputs. It switches the switch element to a non-conducting state, when a second logical level is applied one of the outputs.
