Overview
The TMUXHS4512IRETR is a six-channel, protocol-independent high-speed bidirectional passive switch manufactured by Texas Instruments. It supports differential and single-ended signal transmission with a typical bandwidth of 13 GHz at -3dB. The device operates on a single 1.8V supply voltage, drawing a maximum active current of 500 µA. Key electrical parameters include a maximum on-resistance of 160 Ohms, a propagation delay of 60 ps, and an operating temperature range from -40°C to +125°C. It is housed in a 40-pin WQFN package measuring 3mm x 6mm x 0.4mm.
Feature Summary
- Supports data rates up to 20Gbps for USB4, Thunderbolt 3/4, and DisplayPort 1.4/2.1 (UHBR20).
- Features 5V-tolerant sideband channels compatible with 1.2V, 1.8V, and 3.3V control logic.
- Includes I_OFF protection to prevent leakage current during power rail faults when V_CC is 0V.
Applications
- Personal computers and laptops
- Gaming, home theater, entertainment, and television systems
- Data centers and enterprise computing
- Medical devices
- Wireless infrastructure
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Check for moisture sensitivity level ratings if reflow soldering processes are involved. Ensure the supplier provides valid traceability documents for quality assurance purposes.
Selection Notes
Select this component for designs requiring high-bandwidth switching for USB4 or Thunderbolt interfaces. The 1.8V single-supply operation simplifies power management compared to dual-supply alternatives. Consider the 40-pin WQFN footprint for space-constrained PCB layouts. Verify that the 160 Ohm on-resistance meets the signal integrity requirements of the specific application path.
Part Context
This part belongs to the TMUXHS4512 series of high-speed multiplexer switches. It is functionally similar to the TMUXHS4612RETT but differs in supply voltage requirements, as the latter typically operates at 3.3V. Both devices share the same 40-pin WQFN package and channel count, making them comparable for different power domain applications.
Replacement Considerations
The TMUXHS4612RETT is a pin-compatible alternative within the same family, though it requires a 3.3V supply instead of 1.8V. Verify control logic voltage levels before substitution. No other direct cross-model substitutes are confirmed in the provided documentation.
