Mikroe I2C MUX 7 Click represents a bidirectional selector dedicated to applications with I2C slave address conflicts. The board features the Texas Instruments PI4MSD5V9547 octal bidirectional translating multiplexer controlled by the I2C-bus. 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 standby current, and has no glitch during the power-up sequence.
