The TMUX121 supports I³C standard by maintaining signal integrity through the switch. Table 8-1 details how the TMUX121 specifications make this device optimal for switching I³C signals. Choosing a multiplexer with very low capacitance helps reduces the impact to your total capacitance budget. This can enable more design flexibility keeping the total bus capacitance under 50 pF such as: longer traces, more ICs, multiple buses, and so forth.
