PCA9542APW Integrated Circuit Chip 2-Channel I2C-Bus Multiplexer And Interrupt Logic
Product Description Of PCA9542APW
PCA9542APW 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 the programmable control register. Two interrupt inputs, INT0 and INT1, one for each of the SCx/SDx downstream pairs, are provided. One interrupt output, INT, which acts as an AND of the two interrupt inputs, is provided.
