ADS1114-Q1: In case of different power source between VDD of ADS1114 and pull-up resistors connected to I2C ports of ADS1114

Part Number: ADS1114-Q1
Other Parts Discussed in Thread: ADS1114

Dear experts, 

I have a following quesition about I2C port of ADS1114-Q1.

Is there any damage on the device or any problem when switching on and off VDD of ADS1114-Q1 while supplying voltage(3.3V) to pull-up resistor connected to SDA and SCL port of ADS1114-Q1?

Actually, the power source of VDD of ADS1114 is different from the source of pull-up resistors connected to SDA and SCL.

Thank you in advance for your help.
