LMH0340 - LVDS input at device power down

Hi, Team,

Our customer is using LMH0340. They will power down the device when system is not using LMH0340.
But, in the customer application, there would be a case of LVDS signal input when device powered down.
In this condition, customer monitored 0.7V at VDD pin.(Maybe through the ESD diode to VDD pin)

If you see the absolute maximum ratings, it is inside the specification, but is it OK use in such condition ? Would there be any problem such as latch up ?

Best Regards,
Kawai
