Abstract
A high voltage transmission switch comprises a switching block coupled between a connection terminal to a load and a low voltage output terminal and comprising at least a first switching transistor and a second switching transistor coupled between the connection terminal and the low voltage output terminal and interconnected at a first circuit node; and a driving circuit coupled between a positive low voltage supply reference and a negative high voltage supply reference and having an output terminal connected to the switching block. The driving circuit including at least a first driving transistor coupled between the positive low voltage supply reference and the output terminal and a second driving transistor coupled between the output terminal and the negative high voltage supply reference.
