ABSTRACT:
A cascode I/O driver is described that includes a barrier formed in the shared region between the two transistors. The barrier region allows the I/O driver to be designed to primarily meet I/O requirements. Accordingly, improved operating speeds are achieved. An system is described that includes an I/O driver in parallel with an ESD device. In an embodiment, the I/O driver may assist the ESD device in discharging electrostatic, after the ESD begins conducting.
