ADuM120N: different VDD apply

Question

Hi, I'm finding 2 (or 6) chanel Digital Isolators to send PWM from uC to MotDrivers. 
 I'm looking ADuM120N. 
 Can ADuM120N supports different VDD (VDD1 = 3V3, VDD2 = 5V)? 
 DIN_1, 2 is from 3V3 uC, So, VDD1 can't be 5V (not reach 0.7VDD) 
 While At Isolated VDD2 side has only 5V supply.

Hi, 
 The VDD1 and VDD2 supplies are fully independent. They can be supplied with different voltages as needed by the application. The way the ADuM120N s powered in the diagram is ok.
