ADUM5200 operating voltage


Although being not widely advertised, it seems possible to use ADUM5200 with Vdd1 = 3V3 and Viso = 5V, according to table 24 of Rev B datasheet.
This is my application.

I won't draw any power out from Viso.

What are the risks to do so?

Especially what will be the incidence on Vol and Voh voltage level at the isolated side?

I've noticed that the adum521x family can be also used in that mode (table 25 in DS), although not recommended by ADI.
