I2C bus buffer - PCA9600

Hello community,

 

I am designing a board with PCA9600 chip and in the typical usecase, the bus on master side (SX and SY) will be polarized at 3.3V while PCA9600 VCC pin is not supplied, like RX, TX, RY, TY.

Do you think it will create a problem like power supplying PCA9600 chip from SX pin ?

Or is it acceptable ?

There won't be any communication while the chip is not supplied but just polarization.

 

Thank you for your answer.

 

Best regards,

 

NP
