Abstract
Official abstract text for this publication.
A high voltage switch circuit includes a high voltage switch suitable for transferring a voltage of an input terminal to an output terminal in response to a voltage of a control node; a first transistor suitable for electrically connecting a first node and the control node in response to an inverted activation signal; a second transistor suitable for supplying a first high voltage to the first node in response to an activation signal; a third transistor connected in parallel to the second transistor, and operable in response to the control node; a discharge transistor suitable for discharging the control node; and a first level shifter suitable for changing a swing level of a preliminary activation signal, and generating the activation signal and the inverted activation signal.
