Description

   The PCA9543 is a bi-directional translating switch, controlled by theI2C-bus. The SCL/SDA upstream pair fans of PCA9543 out to two downstream pairs, or channels. Any individual SCx/SDx channels or combination of channels can be selected, determined by the contents of the programmable control register. Two interrupt inputs, INTO  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.
