AD5141 Will powered down device pull down I2C lines?

I'm using multiple AD5141's connected to a single master via I2C. I'd like to be able to power only certain AD5141's while others are powered off but have them all share the same I2C bus. Will the powered down AD5141's pull down the I2C bus (or cause level conflicts from protection diodes?)

 

If so, can I power down VDD but keep VLOGIC enabled to keep the I2C bus enabled?
