The Texas Instruments TUSB8040RKMR is a SuperSpeed USB (USB 3.0) hub controller. It sits between a host USB port and multiple downstream devices, managing enumeration, data routing, and power distribution for the connected peripherals. Typical deployment is in desktop PCs, docking stations, monitors with integrated USB hubs, and industrial equipment that needs a self-powered or bus-powered USB 3.0 hub on the board. The Bulk package means this variant ships in tray or tube — factor that into your pick-and-place feeder setup and MOQ planning.
The TUSB8040RKMR has an Active product status. TI continues to manufacture it with no announced last-time-buy or end-of-life schedule.
What the Bulk package means for your line
The Bulk packaging designation tells you this part is not on tape-and-reel. It ships in tubes or trays, which changes how you feed it into a pick-and-place machine — expect to use tube feeders or a tray shaker, not a reel feeder. If your line is set up for reels only, you may need to budget for a tube-feeder changeover or order a reel-pack variant if one exists in the family. Bulk also typically implies a lower minimum order quantity than tape-and-reel, which can help if you are prototyping or building a small production batch.
