Abstract: A semiconductor device includes an output switching device having an input node, an output node, and a control input node. The control input node enables an input voltage applied to the input node to be switched to the output node. A gate pull-down circuit controls the control input node of the output switching device in response to at least one control signal. The gate pull-down circuit activates the output switching device by raising the voltage level of the control input node above the voltage level of the output node and deactivates the output switching device by clamping the control input node to the voltage level of the output node. A gate pull-up circuit receives an enable signal and generates the at least one control signal to the gate pull-down circuit in response to the enable signal.
