PCA9306: is used for i2c bus level conversion, what should be paid attention to in terms of use?

Hey Elsa,

I ~recently updated the datasheet with a lot of additional information for users to be aware of with this device. You can refer to figure 6 to see the correct implementation with this device for level shifting applications. Figure 7 is the WRONG set up we see most common.

I suggest taking a look at the datasheet and if any specific questions come up, we can address it further here.

Let me know if you still have questions,

-Bobby
