Hi Srinivasu,

Thank you for reaching out.

Yes, you can use VCC1 = 5V and VCC2 = 3.3V. TI's digital isolators can be supplied voltages within the recommended operating conditions on both sides of the device. Since the isolation barrier separates the two sides, each side can be sourced independently with any voltage within recommended operating conditions. Please take a look at this FAQ for more information about using different supply voltages: [FAQ] Can I power the two sides of a digital isolator with different voltages? - Isolation forum - Isolation - TI E2E support forums
