SN75DP128ARTQR

Specialized Overview

The SN75DP128ARTQR is a DisplayPort 1:2 switch manufactured by Texas Instruments, designed for display interface applications. It operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 6 Gbps. The device is housed in a 56-VQFN package with dimensions of 8x8 mm. It functions as a signal buffer and repeater, ensuring backward compatibility with HDMI 1.4b standards. The component is rated for an operating temperature range from 0°C to +85°C and features I²C interface control.

Specialized Feature Summary

• Supports DisplayPort 1:2 switching functionality for dual-display configurations
• Enables backward compatibility with HDMI 1.4b standards
• Provides signal integrity through integrated buffering and retiming capabilities

Specialized Applications

• Dual-monitor laptop designs requiring DisplayPort expansion
• Desktop docking stations utilizing DisplayPort multiplexing
• All-in-one PC display interface circuits
• Portable computing devices with external display output requirements

Specialized Procurement Notes

Verify the specific ordering suffix ARTQR to confirm the 56-VQFN package type and tape-and-reel packaging configuration. Ensure that the procurement source provides official datasheets confirming the 3.0 V to 3.6 V operating voltage range and the 0°C to +85°C industrial temperature rating. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and compliance with RoHS directives.

Specialized Selection Notes

Select this component when a single DisplayPort source must drive two independent displays simultaneously. The SN75DP128ARTQR is suitable for systems requiring HDMI 1.4b backward compatibility alongside native DisplayPort operation. Consider the 56-VQFN footprint for space-constrained PCB layouts. Evaluate the 6 Gbps data rate capability against the bandwidth requirements of the target display resolutions and refresh rates.
