TUSB2551PW

Drivers, Receivers, Transceivers Overview

The TUSB2551PW is an advanced Universal Serial Bus transceiver compliant with USB 2.0 specifications, housed in a 14-pin TSSOP package. It supports full-speed (12-Mbit/s) and low-speed (1.5-Mbit/s) data rates. The device features an integrated bypassable 5-V to 3.3-V voltage regulator for powering via USB VBUS and allows separate I/O supply operation down to 1.65 V. Operating temperatures range from -40°C to 85°C. Key electrical parameters include a VCC(5.0) supply range of 4 V to 5.5 V, a VCC(I/O) range of 1.65 V to 3.6 V, and ESD protection ratings of ±9 kV for both contact and air-gap discharge per IEC-61000-4-2.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest Package Option Addendum to confirm availability status, as production statuses may change. Ensure the selected carrier type matches the required reel width and cavity dimensions for automated assembly processes. Cross-reference the moisture sensitivity level and peak reflow temperature ratings with your facility's soldering profile requirements before placing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring USB 2.0 physical layer compliance with flexible power supply configurations. The dual-supply architecture allows the system interface to operate at core voltages without additional buffering logic. Consider the internal regulator option if a 5-V source is available, or use the regulator bypass mode for direct 3.3-V operation to optimize power consumption in portable equipment designs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TUSB2551 family of advanced USB transceivers manufactured by Texas Instruments. The PW suffix specifically denotes the 14-pin Thin Shrink Small Outline Package (TSSOP). Other variants in the series include the RGT package (QFN), which offers different thermal and footprint characteristics while maintaining identical functional capabilities and electrical specifications.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include TUSB2551APW and TUSB2551A-PWR. Verify that any substitute maintains the same operating temperature range and package outline dimensions to ensure mechanical fit.
