PCA9544 General Description

The PCA9544 is a 1-of-4 bi-directional translating multiplexer, controlled via the I2C bus. The SCL/SDA upstream pair fans out to four 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. Four interrup.
