The I2C MUX 7 Click Board™ is a compact add-on board representing a bidirectional selector dedicated to applications with I2C slave address conflicts. This board features the PI4MSD5V9547, an octal bidirectional translating multiplexer controlled by the I2C-bus from Texas Instruments. Only one SCL/SDA channel can be selected at a time, determined by the contents of the programmable control register. The board powers up with Channel 0 connected, allowing immediate communication between the Master and downstream devices on that channel. The PI4MSD5V9547 also supports hot insertion, has a low Stand-by current, and has no glitch during the Power-Up sequence. This Click board™ is suitable for a wide range of applications from industrial to medical, communications, and automotive systems.
The I2C MUX 7 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
