TMUXHS4446IRETR

Overview

The TMUXHS4446IRETR is a high-speed bidirectional passive crosspoint switch designed for USB Type-C Alternate Mode applications. It supports USB 3.2 Gen2 SuperSpeed and DisplayPort 1.4/2.1 signals up to 10Gbps per lane (UHBR10). The device features a 9.5GHz -3dB differential bandwidth, 6V tolerant SBU pins, and adaptive common mode voltage tracking from 0V to 1.8V. It operates on a single 3.3V supply with active power consumption of 340μA and standby current as low as 0.5μA. Control is achieved via GPIO or I2C interfaces supporting both 1.8V and 3.3V logic levels. The component is housed in a 6mm × 3mm WQFN-40 package and functions within an extended industrial temperature range of −40°C to 105°C.

Feature Summary

Passive bidirectional switching between USB 3.2 Gen2 and DisplayPort 2.1 signals over USB Type-C interfaces
Adaptive common mode voltage tracking maintaining channel stability across the full 0V to 1.8V range
Dual control modes allowing configuration through either GPIO pins or an I2C interface
6V tolerance on sideband unit (SBU) pins to withstand short-to-VBUS events

Applications

PCs and notebooks
Docking stations
Smartphones and tablets
Televisions and home theater systems
Electronic point of sale (EPOS) devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the procurement source provides valid RoHS compliance data and confirms the component meets the specified extended industrial temperature operating range requirements.

Selection Notes

Select this component when designing USB Type-C ports requiring simultaneous support for high-speed USB data and DisplayPort alternate mode signaling. The device is suitable for applications needing flexible control via I2C or GPIO and requires operation within the −40°C to 105°C industrial temperature environment.

Part Context

This part belongs to the Texas Instruments TMUXHS4446 series of high-speed multiplexer switches. It is specifically engineered for USB-C ecosystems to manage signal routing between host/device sides and peripheral displays. The RET suffix indicates the standard reel packaging format for surface-mount assembly.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the same family. Verify pin compatibility and electrical parameters before substituting with other Texas Instruments mux ICs.

FAQ

How does the TMUXHS4446 handle connector flipping?

The device supports automatic signal routing for flipped USB-C connectors by configuring specific high-speed and low-speed channel mappings based on the selected control mode.
