The PCA9543A/43B/43C is a bidirectional translating switch, controlled by the I2C-bus.
The SCL/SDA upstream pair fans 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, INT0 and INT1,
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.
