General Description
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.
