ABSTRACT:
A system having an input and output buffer includes a dynamic driver reference generator to generate dynamic driver reference signals based on a data signal and an IO buffer supply voltage, a level shifter to generate level shifted signals based, in part, on the dynamic driver reference signals, and a driver having at least one stress transistor. The driver dynamically adjusts a voltage across the stress transistor based on at least one of dynamic driver reference signals, the level shifted signals, and a current state of an IO pad.
