8.2.1 Signal Expansion (I3C and I2C)

There are many applications in which microprocessors or controllers have a limited number of I/Os. The TMUX131 solution can effectively expand the limited I/Os by switching between multiple buses to interface them to a single microprocessor or controller. A common application where the TMUX131 is used as a I3C 1:3 multiplexer. In this application, the TMUX131 is used to route communicating between different peripherals from a single controller or driver within a server, as shown in Figure 8-1. The high bandwidth of the TMUX131 will preserve signal integrity at even the fastest communication protocols that may be used in server applications, such as I3C. Also, because I3C is backwards compatible, any of the peripherals can also be I2C, and the TMUX131 will still support it.
