PCA9306: Could PCA9306 support I2C translation 1.5V and 1.8V

Part Number: PCA9306
Other Parts Discussed in Thread: TCA9517

Hi Team,

  Could PCA9306 support I2C voltage translate between 1.5V and 1.8V?

  If not,is there any device or solution can recommend to the customer?

Best Regards,

Nick Dai

  • Hello Nick,

    Technically is should work but our datasheet specifically calls out it was tested with the following.

    We have had customers use it this way in the past but because it doesn't conform to the datasheet, therefore we can't guarantee the operation as such.

  • Hi Francis,

        Thank you for your feedback.

        Could the customer use PCA9306+TCA9517 to translate between 1.8V and 1.5V as below shown?

    Best Regards,

  • Hello Nick,
    Yes, the customer could do something like this. This is perfectly acceptable, though it does add cost. We have a new part coming out soon that would address this situation. We can take this offline and I can share information with you and your customers.
