The datasheet specifies a VIH and VIL for /CE when VIO is 1.8V but not when VIO is 3.3V.
Do the VIH and VIL thresholds scale with the VIO voltage or are they fixed at the values specified in the datasheet?
Ultimately we want to use 3.3VIO for I2C interface but still use the 1.8V generated by VDD to control /CE.
Thanks,
Nick
