... Two interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output INT, which acts as an AND of the two interrupt inputs, is provided. An active-LOW reset input allows the PCA9543 to recover from a 2 situation where one of the downstream I C-buses is stuck in a LOW state ...

... V and 2.7 V, then V 2 effectively clamp the downstream bus voltages. Looking at Figure 5, we see that V PCA9543 supply voltage is 3 lower so the PCA9543 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). ...
