1. A voltage translator, comprising:

  • an output node; and

    circuitry that receives an input signal having a voltage potential, said circuitry operative to provide a HIGH voltage level and a LOW voltage level to said output node in response to the potential of said input signal, said circuitry comprising;

    a plurality of transistors that selectively couple said output node to said HIGH voltage level and said LOW voltage level; and

    voltage protection circuitry coupled to a portion of said plurality of transistors that prevents voltage being applied to said portion from exceeding a predetermined source voltage level.
