摘要： Disclosed is a protection circuit capable of avoiding breakdown of a gate insulating film of a MOSFET and having an appropriate snap-back voltage in terms of reliability. In order to prevent breakdown of a gate insulating film of a MOSFET constituting a stacked protection circuit caused by application of a surge voltage between the gate and the drain of the MOSFET, a single or a plurality of diodes or a MOSFET switch is connected between the gate and the drain of the MOSFET for absorbing the surge voltage. The particular construction permits obtaining a large surge tolerance against the surge voltage entering through, for example, the external power source pad, making it possible to form a protection circuit used in I/O's tolerant to other power sources having an appropriate snap-back voltage against the external surge in assuring the reliability of the semiconductor device.

摘要： A push-pull output buffer contained in an I/O interface circuit of the present invention comprises a P channel MOSFET and a N channel MOSFET. The P channel MOSFET is connected between an I/O node connected to an external circuit through a transmission path and a first potential node to which a first potential is applied. The N channel MOSFET is connected between a second potential node to which a second potential is applied and the I/O node. On/off status of the P channel MOSFET and N channel MOSFET are controlled depending on an input mode for inputting a signal from an external circuit and an output mode for outputting a signal to the external circuit through a transmission path. In this I/O interface circuit, the first and second potentials are terminating potentials, and when input mode is selected, out of the P channel MOSFET and N channel MOSFET, the MOSFET connected to a potential node to which a terminating potential is applied is controlled to be always on.
