HD3SS2521RHUR

Analog Switches - Special Purpose Overview

The HD3SS2521RHUR is a DockPort Controller and Switch manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 3.6V and features a -3dB bandwidth of 6GHz. The device supports USB speeds up to 5000 Mbps and has a typical quiescent current (Iq) of 4500 uA. It is housed in a 56-WQFN package with dimensions of 5x11 mm. The maximum on-resistance is 8 Ohms, and it functions as a passive switch with one channel configured as SPDT. The operating temperature range extends from 0°C to 70°C.

Analog Switches - Special Purpose Feature Summary

• Integrates DockPort controller functionality with high-speed signal switching capabilities for USB Type-C applications.
• Supports bidirectional data transmission with low on-resistance for signal integrity preservation.
• Designed for surface-mount installation in compact electronic devices requiring USB interface management.

Analog Switches - Special Purpose Applications

• USB Type-C docking stations
• Laptop and tablet connectivity hubs
• Peripheral connection interfaces

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix RHUR against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements of 3V to 3.6V. Check moisture sensitivity level (MSL 3) handling procedures during assembly. Confirm lead-free status and RoHS compliance for regulatory adherence. Validate pinout alignment with PCB layout designs prior to procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-channel, high-bandwidth switch with integrated DockPort control is required for USB 3.1 Gen 2 signals. Compare on-resistance and bandwidth against alternatives if signal loss is critical. Consider the 56-WQFN footprint constraints during mechanical design. Evaluate thermal performance within the 0°C to 70°C operational range for the target enclosure environment.

Analog Switches - Special Purpose Part Context

This part belongs to the HD3SS2521 series of DockPort controllers and switches. It is distinct from other HD3SS models like the HD3SS213 or HD3SS3220 which serve different multiplexing roles or support higher data rates such as 10-Gbps USB 3.1. The RHUR suffix specifically denotes the reel packaging format for automated assembly processes.

Analog Switches - Special Purpose Replacement Considerations

HD3SS2521RHUT is a documented variant within the same family, differing primarily in packaging configuration. Verify electrical equivalence and pin compatibility before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
