Abstract
A bi-directional voltage translator (102) includes a first port (300/302), a second port (302/300), and a switch circuit (310). The first port (300/302) communicates a first signal at a first voltage or a second voltage (V.sub.1 /V.sub.2). The second port (302/300) communicates a second signal at the first voltage or a third voltage (V.sub.2 /V.sub.1). The second and third voltages (V.sub.1 /V.sub.2) are different. The switch circuit (310) is coupled to the first port (300/302) and the second port (302/300). The switch circuit (310), responsive to the first signal at the first voltage and the second signal at the third voltage (V.sub.2/ V.sub.1), communicates to the second port (302/300) the second signal at the first voltage. The switch circuit (310), responsive to the second signal at the first voltage and the first signal at the second voltage (V.sub.1 /V.sub.2), communicates to the first port (300/302) the first signal at the first voltage.
