The PCA9542A is a 1-of-2 bidirectional translating multiplexer, controlled via the I2C-bus.The SCL/SDA upstream pair fans out to two SCx/SDx downstream pairs, or channels.Only one SCx/SDx channel is selected at a time, determined by the contents of theprogrammable control register. Two interrupt inputs, INT0 and INT1, one for each of theSCx/SDx downstream pairs, are provided. One interrupt output, INT, which acts as anAND of the two interrupt inputs, is provided.
