    Hi Eric,

    Yes, ISO7321, ISO7841 & most other digital isolators at TI can operate at 5V VCC1 & 3.3V VCC2. Please note that VCC1 and VCC2 supply voltages can independently be supplied with any voltage in their operating voltage. For ISO78xx & ISO77xx, VCC1 & VCC2 can be anywhere between 2.25V & 5.5V independently. Thanks.
