take the level-shifter in usb-balster for example: one side of the shifter is supplied by the power derived from usb, which is always avaliable.

the other side of the shifter is powerd by the target board, which is available only when connect to target board. and the voltage from the target board can vary from 3.3V to 1.2V.

that's what i want the max-ii to do. according to your reply, this is also possible. thanks
