Appropriate voltage for IOVcc of AD5791 DAC

I am having 5V to Vcc pin of the DAC.  And in-coming digital logic level is 3.3V.  What would be suggested IOVcc voltage?


As suggested on page 26 of datasheet, IOVcc and Vcc are tied together, I have tried tie them together and connected to 3.3V.  However it is not seem working.   Should IOVcc and Vcc not be connected together for operation?


Thanks for any help and suggestions
