ABSTRACT:
In accordance with the invention, a driver circuit is described that permits a single thin gate oxide process to be utilized where a dual oxide process may normally be necessary. Circuits employing only thin gate oxide devices are used as the design basis for a single product with a single set of tooling and manufacturing process to operate within the same timing specifications for a core voltage output drive as well as for a higher system drive.
