I've looked at articles detailing I2C level shifting and referencing the below figure I have a question.
If the gates of the FETs were driven by 2.5V and everything else remained the same, would the level shifting still work?
I would think a low from the 3.3V side would propagate but a low from the 5V would not get through.
At what low-side voltage or gate voltage would this circuit not work?
thanks
