I want to use PCA9306 in switch configuration, i.e Vref1=Vref2. As per datasheet, when EN pin goes lows, the SCL,SDA line are disconnected/high impedance. But what happens when Vref1 or VREF2 (or both) are not available/present, what will be status of I2C lines? whether they will be in high impedance state or not?
