Classification: CPC H | IPC H

Claim 8:
9. A method, comprising:
supplying an input voltage from an input pad of an integrated circuit to a Schmitt trigger of the integrated circuit;
supplying a charging current from a main transistor branch of the Schmitt trigger to an intermediate node of the Schmitt trigger responsive to a transition of the input voltage from a high input value to a low input value; and
supplying a supplemental charging current from a parallel transistor branch of the Schmitt trigger to the intermediate node responsive to the transition of the input voltage from a high input value to a low input value, wherein a pass transistor is coupled between the input pad and the parallel transistor branch, a switching storage element is coupled to a gate terminal of the pass transistor, and a control and reset circuit is coupled to the switching storage element, the pass transistor, and the parallel transistor branch.
