Abstract
An output circuit comprising an output stage and a control signal generator. The output stage is constituted by a first P-channel MOS transistor and an N-channel MOS transistor. The control signal generator generates a signal for driving the gates of the MOS transistors, it comprises a NAND gate, a NOR gate NOR1 and an inverter INV1. The first P-channel MOS transistor of the output stage has a source and a back gate which are isolated in terms of potential. A second P-channel MOS transistor is provided, whose source-drain path is connected between the back gate and gate of the first P-channel MOS transistor incorporated in the output stage.
