Abstract: Provided is a circuit that sets a voltage of a failsafe node. The circuit includes a first voltage setting transistor configured to operate in a conductive state to set a voltage of the failsafe node to a supply voltage of a supply voltage node. The circuit includes first and second control transistors configured to control the first voltage setting transistor to operate in the conductive state in response to both the supply voltage and a pad node voltage of a pad node corresponding to logical one and control the first voltage setting transistor to operate in a nonconductive state in response to one of the supply voltage or the pad node voltage corresponding to the logical one and another one of the supply voltage or the pad node voltage corresponding to logical zero.
