Abstract
Disclosed is a semiconductor integrated circuit device that includes an output circuit with power thereof supplied from one power supply system, an input circuit with an input terminal thereof connected to an output terminal of the output circuit through a signal line and with power thereof supplied from other power supply system different from the one power supply system, and a circuit that restrains a current flowing from the output circuit into the signal line when an ESD stress is applied from the output circuit to a signal transmitting/receiving portion of the input circuit.
