TMUXHS4446RETT

Overview

The TMUXHS4446RETT is a high-speed bidirectional passive crosspoint switch designed for USB Type-C Alternate Mode applications. It supports USB 3.2 Gen2 SuperSpeed signals up to 10Gbps and DisplayPort 1.4/2.1 signals up to 10Gbps per lane (UHBR10). The device features a 4:6 mux configuration with a 9.5GHz -3dB differential bandwidth. It operates on a single 3.3V supply, consuming 340μA in active mode and 0.5μA in standby. The component includes adaptive common-mode voltage tracking from 0V to 1.8V and 6V tolerant SBU pins. It supports both GPIO and I2C control modes 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 consistency across the full voltage range
Dual control flexibility allowing configuration via GPIO pins or I2C interface
Robust protection with 6V tolerance on sideband unit pins against short-to-VBUS events

Applications

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

Procurement Notes

Verify the specific suffix RETT corresponds to the WQFN-40 package and reel packaging format as defined in the manufacturer's orderable information. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the design accounts for the specified humidity sensitivity level during storage and assembly processes. Validate that the selected operating voltage aligns with the recommended 3.3V supply specification.

Selection Notes

Select this component when designing USB Type-C ports requiring simultaneous support for high-speed data and display alternate modes. The device is suitable for both source and sink configurations in host or device applications. Consider the 9.5GHz bandwidth and low insertion loss for maintaining signal integrity at 10Gbps rates. Evaluate the thermal performance characteristics if the application involves sustained high-frequency operation in enclosed spaces.

Part Context

This part belongs to the Texas Instruments TMUXHS4446 series of multiplexer switches. It is specifically engineered for high-speed analog signal routing in modern connectivity standards. The series addresses the need for flexible signal path management in compact electronic devices utilizing USB-C connectors.
