7.1 Overview

The TMUXHS221F is a 1.2V Logic Compatible, bidirectional low-power dual port, high-speed, USB 2.0 analog switch with integrated protection for USB Type-C systems. The device is configured as a dual 2:1 or 1:2 switch. It is optimized for handling the multiplexing solutions for USB 2.0 D+/- lines as well as a cross point switch solution for SBU lines in a USB Type-C system as shown in Figure 7-1.

The TMUXHS221Fis an analog passive mux that can work for any low-speed, high-speed, differential or single-ended signals. The signals must be within the allowable voltage range of −0.3 to 3.6V. The device is optimized for eUSB2 and USB 2.0 LS, FS, and HS signaling. The dynamic characteristics of the device allow high-speed switching with minimal attenuation to the signal eye diagram and little added jitter. While the device is recommended for the interfaces up to 3Gbps, actual data rates where the device can be used highly depends on the electrical channels. For low loss channels where adequate margin is maintained, the device can potentially be used for higher data rates.

The TMUXHS221F also works in traditional USB systems that need protection from fault conditions such as automotive and applications that require higher voltage charging. The device maintains excellent signal integrity through the optimization of both RON and BW while protecting the system with 28V OVP protection. The OVP implementation is designed to protect sensitive system components behind the switch that cannot survive a fault condition where VBUS is shorted to the SBU pins or the D+/D- pins on the connector.
