VDD Range for digital isolators

Hi,

Many of the ADuM digital isolators, i.e. ADuM3300, have a 3V and 5V operating range for VDD1 and VDD2. The 3V range is 2.7 - 3.6V and the 5V range is 4.5 - 5.5V.

Is the device guaranteed to operate if the VDD supply is between 3.6 - 4.5V, albeit at 3V specs?

Thanks
