DP83849I Power Supply IOVDD

Dear team,

Absolute max rating for supply voltage -0.5 V to 4.2 V and recommended supply voltage is 3.3 V ± 0.3V as stated in datasheet.

Does it mean this device can support voltage supplied other than 3.3V? For example 1.8V? What is the result?

What is the DC spec for IOVDD 1.8V if it is supported?

Hope to hear from you soon.

    As noted in the datasheet, "Absolute maximum ratings are those values beyond which the safety of the device cannot be specified. They are not meant to imply that the device should be operated at these limits." The allowable supply voltage is 3.3V as indicated in the Recommended Operating Conditions section of the datasheet.
