SN75DP128RTQR

Specialized Overview

The SN75DP128RTQR is a DisplayPort 1:2 switch manufactured by Texas Instruments, designed to route a single DisplayPort input signal to one of two output ports. It supports data rates up to 2.7 Gbps per lane and operates within a supply voltage range of 4.5 V to 5.25 V. The device is housed in a QFN-56 package (8x8 mm) suitable for surface-mount installation. It functions as a compact switch for connecting PCs to video displays, enabling flexible display configurations in portable and desktop systems.

Specialized Feature Summary

• Routes one DisplayPort input to one of two outputs
• Supports 2.7 Gbps data rate per lane
• Compact QFN-56 surface-mount package

Specialized Applications

• Connecting PCs to video displays
• Portable computer display routing
• Desktop system display expansion

Specialized Procurement Notes

Verify the exact suffix RTQR against the manufacturer's official datasheet SLLS893 to confirm pinout and electrical specifications. Ensure compatibility with the system's 4.5 V to 5.25 V power supply requirements. Check for moisture sensitivity classification and reflow soldering profile compliance before integration into the PCB assembly process.

Specialized Selection Notes

Select this component when a single DisplayPort source needs to drive one of two displays simultaneously. It is suitable for applications requiring 2.7 Gbps bandwidth per lane. Consider the QFN-56 package size for space-constrained designs. Verify that the host controller supports the necessary control signals for switching between output ports.
