TCA9554: I2C Bus for VCC=0V operation

Guru 19675 points

Part Number: TCA9554

Please let me know about I2C Bus operation for Vcc:0V, which is correct for below thinking?

(I2C bus is turn on, Vcc is 0V)

①The other I2C Bus are supply normal voltage.

②Bus power is sink to GND, and I2C Bus Line are bad effect (do not move, etc).

Best regards,

Satoshi
