More Information

The PCA9543A is a dual bidirectional translating switch controlled by the I2C bus. The SCL/SDA upstream pair fans out to two downstream pairs, or channels. Either individual SCn/SDn channel or both channels can be selected, determined by the contents of the programmable control register. Two interrupt inputs ( INT1– INT0), one for each of the downstream pairs, are provided. One interrupt output ( INT) acts as an AND of the two interrupt inputs.
