PCA9306: Suitable I2C level shifter solution

Charles Zhang1

Part Number: PCA9306
Other Parts Discussed in Thread: ISO1640

Hi Team,

Can I2C level shifter(like PCA9306) deal with the logic signal with 1-V offset from upstream device?

Or is there nay workaround to deal with I2C signal with 1-V offset?

All logic level shifters have a common ground.

The simplest solution for this would be an I²C isolator like the ISO1640.
