8.1 Application Information

There are many USB applications in which the USB hubs or controllers have a limited number of USB I/Os or need to route signals from a single USB connector. The TMUXHS221F solution can effectively expand the limited USB I/Os by switching between multiple USB buses to interface them to a single USB hub or controller or route signals from on connector to two different locations.

As systems shiftingaway from using redrivers and SoC directly having high drive capabilities, passive multiplexing solutions like TMUXHS221F help adding capabilties of cross point muxes (SBU switch) or USB2.0 Data multiplexing with Over voltage protection feature so that muxes can directly interface with USB ports avoiding use of port protection ,saving area.

TMUXHS221F comes with extended 1.2V control logic not only makes it compatible with latest generation of low nm SoCs but also allows sufficient noise margin for system designers and hence easy usage of TMUXHS221F.
