... Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable Control Register. An active-LOW reset input allows the PCA9548 to recover from a situation where one of the downstream I state. Pulling the RESET pin LOW resets the I2C state machine and causes all the channels to be deselected as does the internal power on reset function ...

... V and 2.7 V, then V 2 effectively clamp the downstream bus voltages. Looking at Figure 5, we see that V PCA9548 supply voltage is 3 lower so the PCA9548 supply voltage could be set to 3.3 V. Pull-up resistors can then be used to bring the bus voltages to their appropriate levels (see Figure 12). ...
