Overview
The TMUXHS4512IRETT is a high-speed bidirectional passive switch in mux or demux configurations. It supports data rates up to 20Gbps for USB4 and DisplayPort 1.4/2.1 (UHBR20). The device features six differential channels with a typical on-resistance of 8.8Ω and a -3dB differential bandwidth of 13.0GHz. It operates on a single 1.8V supply, consuming 500μA active current and 2μA standby current. The IRETR suffix indicates an industrial temperature range (-40°C to 125°C) and WQFN-40 packaging.
Feature Summary
- Protocol agnostic design supporting USB4, Thunderbolt 3/4, and DisplayPort interfaces
- Integrated charge-pump technology enabling low on-state resistance
- IOFF protection prevents leakage current during supply rail collapse
- Sideband channels are 5.5V tolerant and support 1.2V, 1.8V, and 3.3V control logic
Applications
- PC and notebooks
- Gaming, home theater & entertainment, and TV
- Data center and enterprise computing
- Medical applications
- Test and measurements
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Confirm that the component meets RoHS compliance requirements for your target market. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the internal FET switches.
Selection Notes
Select this component when interfacing high-speed differential signals up to 20Gbps. Ensure the system power supply remains within the 1.62V to 1.98V range. Verify that the common-mode voltage of the signal paths falls between 0V and 1.0V for the high-speed data pins. Consider the 40-pin WQFN package size for PCB layout constraints.
Part Context
This part belongs to the Texas Instruments TMUXHS4512 family of high-speed multiplexer switches. The 'I' designation specifies the industrial operating temperature range, while 'RET' identifies the 40-pin WQFN package with a 0.4mm pitch. The device is designed as a generic analog differential passive mux/demux for modern display and connectivity standards.
Replacement Considerations
Check the TMUXHS4412 for a 4-channel variant or the TMUXHS4612 for a 6-channel version with different voltage tolerances. Ensure any substitute maintains the required 13GHz bandwidth and 20Gbps data rate support. Verify pin compatibility if replacing within the same package footprint.
