DS90LV049: Reverse current to VDD

Zeming Kong

Part Number: DS90LV049

Hi team,

A quick question, if power supply is off but signal is still inputted, will there be any reverse current to VDD?

Thanks for your support in advance.

Best regards

HI Zeming,

Is this a differential input or single-ended input?

Hi Malik,

It is differential input. BTW, what will happen if it is a single ended input?

Best,

Hi Zeming,

In both cases there will be some reverse current to Vcc. This part has 300 kohm internal pull-up.
