Logic circuit device comprising at least one digital input

A logic circuit device comprising at least one digital input furnished with a fuse (FUS) being, in the closed state, suitable for applying an electrical input voltage of the logic circuit corresponding to a first logic state from among the logic states 0 and 1, and, in the definitive open state, suitable for applying an electrical input voltage of the logic circuit corresponding to the second logic state, opposite to the first logic state, from among the logic states 0 and 1, said fuse (FUS) being suitable for being placed definitively in the second logic state by injection of a current greater than a threshold current (CS), in which said digital input comprises, furthermore, a first resistor (R1) for maintaining input electrical potential corresponding to the second logic state, and an assembly comprising a second resistor (R2) for limiting current in the fuse (FUS) and a third electrical test input point (Ptest) which are connected electrically, said assembly being connected electrically between the fuse (FUS) and the first resistor (R1) in which said digital input comprises, furthermore, a second electrical input point (Pmef) for placing the fuse (FUS) in the definitive open state, directly connected electrically to an electrical bond between the first resistor (R1) and the fuse (FUS).
