Abstract

An input buffer system has an input clipping circuit. The input clipping circuit has a high voltage input and uses transistors all being the thin oxide type transistors. A high voltage detect circuit is coupled to the input clipping circuit. An input buffer circuit is coupled to the input clipping circuit and has a low voltage output range.
