... Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs. An active-LOW reset input allows the PCA9545 to recover from a 2 situation where one of the downstream I C buses is stuck in a LOW state ...
