A Josephson device applicable to a down-edge detecting circuit and to a sense circuit comprises a first gate circuit and a second gate circuit each incorporating Josephson junctions, with an input line of the first gate circuit and a first input line of the second gate circuit serially connected to each other and an output line of the first gate circuit connected to a second input line of the second gate circuit so as to allow the second input line to flow an input current in the direction opposite the current flowing through the first input line. With this device, a down-edge detecting circuit which provides a wide operating margin for the gate current and permits high density circuit integration can be realized. The device can further be used to form a sense-bus circuit.
