TUSB2551ARGTR

Drivers, Receivers, Transceivers Overview

The TUSB2551ARGTR is an Advanced Universal Serial Bus Transceiver manufactured by Texas Instruments, designed for USB 2.0 compliance. It operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 480 Mb/s for High-Speed operation, as well as 12 Mb/s for Full-Speed and 1.5 Mb/s for Low-Speed modes. The device integrates a built-in charge pump to generate the necessary internal voltages for signal transmission without external components. It functions as a bidirectional transceiver with one function unit and two ports, housed in a 14-pin TSSOP package suitable for surface-mount applications.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a charge pump circuit to eliminate the need for external voltage generation components.
• Supports full USB 2.0 protocol compliance including High-Speed, Full-Speed, and Low-Speed data transfers.
• Features enable control logic for power management and operational state configuration.

Drivers, Receivers, Transceivers Applications

• Host-to-device connectivity interfaces in personal computers and peripherals.
• Universal Serial Bus hub implementations requiring signal conditioning.
• Portable electronic devices utilizing USB 2.0 connections for data exchange.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ARGTR' against the manufacturer's official documentation to confirm the tape-and-reel packaging quantity and temperature grade specifications. Ensure that the ordering information matches the exact part number required for the intended assembly process, as suffix variations may indicate differences in reel size or environmental ratings rather than functional changes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a compact solution for USB 2.0 signal translation is required without external passive components for voltage boosting. Consider the 14-TSSOP package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental requirements of the final system, as industrial or extended grades may require different suffixes.

Drivers, Receivers, Transceivers Part Context

This device belongs to the TUSB2551 family of USB transceivers from Texas Instruments. It serves as a bridge between USB host controllers and physical bus lines. Related variants include the TUSB2551A, which offers similar functionality with potential updates in manufacturing processes or minor electrical characteristics, while maintaining pin compatibility for design reuse.

Drivers, Receivers, Transceivers Replacement Considerations

The TUSB2551APWR is a direct pin-compatible alternative within the same family, differing primarily in the packaging style (TSSOP vs. potentially other variants depending on specific sub-models) or reel configuration. Verify electrical parameters such as propagation delay and output drive strength before substitution to ensure signal integrity remains within USB 2.0 specifications.
