TLV7034-Q1: Can input pins have voltage applied if VCC is disabled?

Part Number: TLV7034-Q1

Hello,

My customer has a use case where the input pins may see a voltage on the input pins (<7V) when VCC is disabled. The absolute max table seems to indicate that this condition may not cause damage, however it would violate the recommended operating condition for IN+/-. Is this use case okay?

Thanks,
Matthew Guibord

    Hello Matthew, 

    Thank you for your question and you are correct. The TLV7034-Q1 will remain undamaged with 7V on the input pins and 0V on VCC. 

    The TLV7034-Q1 has fault tolerant inputs so it is in a high-Z state during power up and VCC = 0V.

    Best Regards,
