Abstract

A transmission channel includes at least one high voltage buffer block having buffer transistors and respective buffer diodes, being electrically coupled between respective voltage reference terminals, these buffer transistors being also coupled to a clamping block, in turn including clamping transistors connected to at least one output terminal of this transmission channel through diodes coupled to prevent the body diodes of the clamping transistors from conducting. The transmission channel includes at least one reset circuit having diodes and being electrically coupled between circuit nodes of the high voltage buffer block and of the clamping block, these circuit nodes being in correspondence with conduction terminals of the transistors comprised into the high voltage buffer block and into the clamping block.
