Colleagues,
Is there a good method for level-translating the I2C in the following situation?
The I2C bus master and most of the slaves are powered from a +3.3V rail.
One peripheral is powered from a different rail which can vary between +2.8V and +4.2V. Notice that this rail can be above or below the +3.3V rail.
I've noticed that PCA9306 requires that VREF1 < VREF2 .
Any suggestion, insight or reference is really appreciated!
Sincerely,
- Nick
