Abstract
An output stage for electronic circuits with high voltage tolerance and of the type comprising an output buffer made up of a complementary transistor pair comprising a P-channel MOS pull-up transistor and an N-channel MOS pull-down transistor. The transistors are connected together to make up an output terminal of the stage which comprises in addition a switch having an input connected to the output terminal of the stage and an output connected to the control terminal of the pull-up transistor to drive said control terminal in a state of extinction of the output buffer.
