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 (V1/V2). The second port (302/300) communicates a second signal at the first voltage or a third voltage (V2/V1). The second and third voltages (V1/V2) 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 (V2/V1), 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 (V1/V2), communicates to the first port (300/302) the first signal at the first voltage.

Abstract: Un traductor de tension bidireccional (102) incluye un primer puerto (300/302), un segundo puerto (302/300), y un circuito conmutador (310). El primer puerto (300/302) transmite una primera señal a una primera o segunda tension (V1/V2). El segundo puerto (302/300) transmite una segunda señal a la primera o tercera tension. La segunda y tercera tensiones (V1,V2) son diferentes. El circuito conmutador (310) está acoplada al primer puerto (300/302) y el segundo puerto (302/300). El circuito conmutador (310), en respuesta a la primera señal a la primera tension y la segunda señal a la tercera tension (V2/V1), transmite al segundo puerto (302/300) la segunda señal a la primera tension. El circuito conmutador (310), en respuesta a la segunda señal a la primera tension y la primera señal a la segunda tension (V1/V2), transmite al primer puerto (300/302) la primera señal a la primera tension.
