ABSTRACT:
A semiconductor integrated circuit device is disclosed, which comprises power supply system circuits, in which power supply terminals and/or ground terminals are separated from each other between the power supply system circuits, an electrostatic discharge protecting circuit, an internal circuit provided in each of the power supply system circuits, an internal signal transmitting line, a surge input detecting circuit, and at least one of an input protecting circuit which is provided at an input side of the internal circuit and which limits a voltage of a signal transmitted from the internal signal transmitting line, and an output logic setting circuit which is provided at an output side of the internal circuit and which sets a logic level of a signal outputted to the internal signal transmitting line to a low level when the surge input detecting circuit has detected a surge input.
