PCA9615: I have detected the Vol of SDA(or SCL) that was about 0.7V. I want to know how can I cutdown the Vol. Thank you !
I think you will need to change the size of the pull-up resistors and it should help. Please refer to the User Manual https://www.nxp.com/docs/en/user-guide/UM10204.pdf section 7.1 page 55.
With best regards,
