8.2 Typical Application 1

TMUXHS221F SBU switch. The TMUXHS221F is used as a SBU cross point mux by connecting it in the configuration where the channels are shorted in the way show below. It helps using the SBU (side band usage)pins in the USBC connector for various protocol communication like DisplayPort , Debug , PCIe, and Audio Codec. This allows all protocol support via single USBC connector. SBU mux is used as a cross point mux which helps in determining a consistent +ve and -ve configuration of the SBU1/2 to the Auxn or Auxp pins of the ALT PHY. The TMUXHS221F does not have pull-down/Pull up resistors on SEL and OE. Hence, they are advised not to be floated to avoid garbage data transfer or high current.
