Hi team,
Just confirm, Can PCA9306 support 1Mhz I2C communication signal?

Hi Hale,
Yes, this is possible. The design considerations are on the external pullups/ output capacitive load at the I/O channels that help to achieve 1MHz speeds. See https://www.ti.com/lit/an/slva689/slva689.pdf?ts=1740597887318&ref_url=https%253A%252F%252Fwww.google.com%252F for additional details regarding PU resistor sizing to help support 1MHz timing requirements.
Regards,
Jack
