Abstract
Output buffer (100) translates input signals from one voltage range to a second voltage range. The second voltage range may be identical to the first range or may be greater. The particular range is programmable by one of several ways. This feature makes output buffer especially suitable for use in devices which must be compatible with two voltage ranges. Output buffer uses a bias generator (110) to limit the voltage across the gate oxide of its various transistors to a level which is consistent with the first voltage range.
