ABSTRACT:
The invention concerns a circuit protected against transitory perturbations, comprising a combinatorial logic circuit (10), having at least an output (A); a circuit (20) generating an error control code for said output, and a storage element (24) provided at said output, controlled by the circuit generating a control code to be transparent when the control code is correct, and to maintain its status when the control code is incorrect.
