Hi

Thanks

    Hi Devendra,

    Thank you for your interest in this part.

    The ratings for the VDD and VSS pins in the datasheet are relative to each other, so as long as you keep VDD-VSS voltage within the recommended operating conditions given in the datasheet a negative bias is acceptable. 

    If this answers your question please click the green button, or if not let us know how we can help you further. 

    Regards,

    Daniel
