Overview
The TMUXHS4612RETR is a high-speed differential multiplexer switch IC from Texas Instruments, featuring six channels in a 2:1 configuration. It supports data rates up to 20Gbps for USB4 and UHBR20 DisplayPort, as well as 12Gbps HDMI. The device operates on a single 3.3V supply with a voltage range of 3V to 3.6V. Key electrical parameters include a maximum on-resistance of 110 Ohms, a -3dB bandwidth of 13GHz, and propagation delay of 60ps. Active power consumption is 800µA, reducing to 32µA in shutdown mode. It is housed in a 40-pin WQFN package (3mm x 6mm) and functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports high-speed differential signaling up to 20Gbps for modern interface standards including USB4 and DisplayPort 2.1.
- Provides low insertion loss and minimal signal degradation with a typical on-resistance of 8.8 Ohms.
- Includes sideband channels capable of tolerating 5V levels, supporting control signals like I2C and UART.
- Features ultra-low active and standby power consumption with integrated I_OFF protection against current leakage.
Applications
- Laptops and personal computers
- Data centers and enterprise computing systems
- Gaming consoles and home entertainment devices
Procurement Notes
Verify the specific suffix 'RETR' against the manufacturer's official datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure compatibility with the required 3.3V logic levels and check moisture sensitivity classification before assembly. Confirm that the 40-pin WQFN footprint matches the design layout requirements.
Selection Notes
Select this component when designing systems requiring six-channel switching for high-bandwidth interfaces such as USB4 or DisplayPort 2.1. It is suitable for applications needing wide common-mode voltage ranges and robust sideband handling. Consider the thermal performance of the WQFN package if operating near the upper temperature limits.
Part Context
This part belongs to the TMUXHS4612 series of high-speed analog switches. It is designed specifically for next-generation video and data transmission protocols. The device integrates multiple switches into a compact form factor, replacing discrete solutions to save board space while maintaining signal integrity at multi-gigabit speeds.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as the TMUXHS4612RER, which may differ only in packaging format. Verify that any substitute maintains the 20Gbps data rate capability and 3.3V operation requirements.
