Abstract
An integrated circuit includes a pass gate having an input and an output. An NMOS pass transistor is connected between the input and the output. The drain of the NMOS pass transistor is connected to the input and the source of the NMOS pass transistor is connected to a node between the source of the NMOS transistor and the output of the pass gate. A current clamp is connected between the node and a current sink so as to conduct current to the current sink when the node reaches a threshold value.
