Abstract
A method of implementing bi-directional level translation in an information handling system includes coupling a first device port via a first resistor to a first voltage. A second device port is coupled via a second resistor to a second voltage different from the first voltage. Lastly, a single bipolar junction transistor (BJT) couples the first device port to the second device port, the single bipolar junction transistor including an emitter coupled to the first device port, a base coupled via a third resistor to the first voltage, and a collector coupled to the second device port, wherein the bipolar junction transistor operates as a bi-directional level translator between the first and second device ports.
