LSF0102: Series Usage

Xiao,

What is the application usage you are trying to do?
You could do this, but the driver device will have to sink the current generated from both the cascaded devices.

I need to shift voltage level between two I2C device, but their voltage relationship is not fixed ( A device may be higher or lower than B device ).
So I wanna know if the method above could solve this problem.
What do you think?

The block diagram is as below, with resistance and capacitor omitted.

By the way, according to the datasheet, Vref_B should be higher than Vref_A.

Thanks!
