Hello,
The PCA9671 datasheet states that the input/output pins are "5 Volt tolerant". Is there any issue with connecting an I/O to 3.3 Volts when VDD is not powered?
I note that the input voltage is speccified to a maximum of 5.5 Volts with no reference to the VDD pin. However, I can't find figures for the I/O leakage current when the device is not powered, and don't want to take the answer from the absolute maximum values alone.
Many thanks!
Pete
Hello Pete,
I need to consult this with our design team and will update this thread as soon as I have their feedback.
Thanks for your patience.
Best regards,
Tomas
