TMUXHS4512RETR

Overview

The TMUXHS4512RETR is a high-speed bidirectional passive multiplexer/demultiplexer manufactured by Texas Instruments. It features six differential channels supporting data rates up to 20Gbps, compatible with USB4 and DisplayPort 1.4/2.1 (UHBR20). The device operates on a single 1.8V supply voltage (range 1.62V to 1.98V) and provides a typical on-resistance of 8.8Ω for high-speed pins. It offers a –3dB differential bandwidth of 13GHz and supports common-mode voltages from 0V to 1.0V on data paths. Sideband signals are 5.5V tolerant. The component is housed in a 40-pin WQFN package (3mm x 6mm) with an exposed thermal pad.

Feature Summary

Protocol-agnostic design supporting high-speed differential interfaces like USB4 and Thunderbolt.
Integrated charge-pump technology enables low on-state resistance for minimal signal attenuation.
IOFF protection prevents current leakage during supply rail collapse or power-off states.
Supports independent selection of high-speed data paths and sideband control paths.

Applications

PC and notebook internal display switching
Gaming, home theater, entertainment systems, and TV
Data center and enterprise computing infrastructure
Medical applications and test/measurement equipment
Wireless infrastructure and electronic point of sale (EPOS)

Procurement Notes

Verify the specific suffix RETR corresponds to the required temperature range and packaging format. Confirm that the 40-pin WQFN footprint matches the PCB layout guidelines provided in the datasheet. Ensure ESD handling procedures are followed due to the sensitivity of high-speed I/O pins. Validate that the 1.8V supply requirement aligns with the system's power architecture before integration.

Selection Notes

Select this component when a 6-channel mux is required for 20Gbps interfaces such as DisplayPort UHBR20 or USB4. Consider the 1.8V single-supply constraint and the 0V to 1.0V common-mode voltage limitation for high-speed data paths. Evaluate the 40-pin package size against available board space. Verify that sideband channel 5.5V tolerance meets the system's control logic requirements.

Part Context

This part belongs to the TMUXHS4512 family of high-speed analog switches. The RETR suffix indicates the reel packaging variant of the industrial temperature grade (–40°C to 125°C) device. It serves as a generic passive mux/demux solution for protocol-agnostic high-speed signaling applications requiring low insertion loss and high isolation.
