Abstract

Circuit and method aspects are provided for voltage level translation circuit for an output driver. In a circuit aspect, a circuit includes an input mechanism for receiving an internal data signal of a first predetermined voltage range, at least two stacked transistors coupled to the input mechanism, and a bias generator coupled to the input mechanism and the at least two stacked transistors, the bias generator ensuring that the at least two stacked transistors operate below a predetermined maximum device voltage. The circuit further includes an output mechanism coupled to the at least two stacked transistors, the output mechanism providing an external signal of a second predetermined voltage range.
