2.3 When to Use Passive Multiplexer for Type-C Alt Mode application

The Type-C Alt Mode switch can be either a passive or redriver multiplexer. A passive switch is bidirectional so that the switch can be placed on either the source or sink side.

Other than the cost is much cheaper than redriver switch, the power consumption of TMUXHS4446 is only 2mW comparing to 0.5W power consumption for typical redriver switch.
