TMUXHS4446IRETT

Overview

The TMUXHS4446IRETT 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 power of 0.5μA in GPIO mode. Control is achieved via GPIO or I2C interfaces supporting both 1.8V and 3.3V logic levels. The component is housed in a 3mm × 6mm WQFN-40 package and functions within an extended industrial temperature range of −40°C to 105°C.

Feature Summary

Passive bidirectional switching between USB and DisplayPort 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 I2C controllers
6V tolerance on sideband unit (SBU) pins to withstand short-to-VBUS events

Applications

PCs and notebooks
Docking stations
Smartphones and tablets
Gaming devices and TVs
Electronic point of sale (EPOS) systems

Procurement Notes

Verify the specific suffix 'IRETT' corresponds to the required tape-and-reel packaging format and moisture sensitivity level. Confirm that the 3.3V operating voltage aligns with the system design requirements. Ensure the I2C logic level selection matches the connected controller using the MODE1 pin configuration. Validate that the WQFN-40 package dimensions fit the target PCB layout constraints.

Selection Notes

Select this component when designing USB-C ports requiring simultaneous support for USB 3.2 Gen2 and DisplayPort Alt Mode at 10Gbps speeds. It is suitable for applications needing flexible control via I2C or direct GPIO connections. Consider the 6V SBU tolerance for robust protection against connector faults. Ensure the design accommodates the 3.3V single-supply requirement and the specified thermal characteristics for the intended operating environment.

Part Context

This part belongs to the Texas Instruments TMUXHS4446 series of high-speed multiplexer switches. It is specifically engineered for USB Type-C ecosystems to manage signal routing between host/device sides and peripheral displays. The device integrates both high-speed data path switching and low-speed auxiliary channel management into a single compact solution.
