ABSTRACT:
An integrated circuit includes a logical part and a buffer part. A voltage clamping circuit is provided in parallel with a driver transistor of the logical part of the integrated circuit. The high level of the internal logical circuit is linked to the voltage of a first source power supply that is supplied to the driver transistor. A plurality of diodes may be used, connected in parallel as the voltage clamping circuit. A voltage clamping circuit may be formed alternatively by using a plurality of field transistors, each of the transistors using the gate as an anode and the short-circuited source and drain as a cathode, and the anode and the cathode are connected in series. An input buffer circuit of differential type configuration is used, and by inputting the voltage of a first source power supply to a reference voltage part of the input buffer circuit, the level conversion of an input voltage is made to be linked to variations of the voltage of the source power supply.
