Procurement Notes
Verify the component status carefully before procurement. Official documentation indicates this specific part number is discontinued or obsolete. Confirm availability through authorized distributors or secondary market suppliers, as direct manufacturing supply may be limited or unavailable. Ensure compatibility with existing design requirements if substituting from current inventory.
Selection Notes
Select this component only when designing for legacy systems requiring first-generation USB 3.0 redriver functionality. Evaluate the 24-VQFN package constraints against board space limitations. Consider that newer generations of redrivers may offer improved performance or availability; verify if alternative TI models meet the same electrical specifications for new designs.
Part Context
This device belongs to the HPA02286 series family of USB interface integrated circuits. It serves as a signal conditioning element within the broader category of USB Redrivers produced by Texas Instruments. The component addresses signal degradation issues inherent in high-frequency digital communication paths.
Replacement Considerations
The SN65LVPE502ARLLR is listed as an alias for this part number. Verify pinout and functional equivalence before substitution. No other official replacement part numbers are confirmed in the provided documentation.
