PI4MSD5V9547 8-Channel I2C bus multiplexer

The PI4MSD5V9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus. The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only one SCx/SDx channel can be selected at a time, determined by the contents of the programmable control register. The device powers up with Channel 0 connected, allowing immediate communic.
