Abstract
An intrinsically safe digital circuit has at least two output signals and at least four input signals for detecting a potential error in the circuit and/or in one of its input signals, the at least four input signals forming two input signal pairs inverted in a double-track manner, and the at least two output signals forming an output signal pair inverted in a double-track manner. The output signal pair transmits a piece of information which is identical to the one of an input signal pair, when the error is not present.
