It accepts the 5 Gbps data stream from the host controller, applies input equalization and output de-emphasis, and re-drives a clean signal to the connector or downstream device. The 290 ps propagation delay is low enough that it does not eat into the USB 3.0 link timing budget. It operates from a 3 V to 3.6 V supply and draws 43.8 mA typical. The 1.25 pF input capacitance keeps the stub loading on the host side minimal. It is rated for the industrial temperature range of -40°C to 85°C, so it fits outdoor or factory-floor equipment where the ambient can run hot. ## Active, no LTB risk — but verify the date-code font The TUSB501DRFR shows as Active in the current lifecycle stage. That said, this is a popular USB 3.0 Gen 1 redriver and has been in the channel long enough that gray-market reels with mismatched date-codes do turn up. If you are buying outside the authorized TI distribution chain, the laser etch on the 8-WSON package is a quick fingerprint: the font, spacing, and orientation should match TI's plant marking for the date-code week. Any sanding, re-mark, or inconsistent pad geometry on the exposed paddle is a red flag. ## Package and layout — 8-WSON with exposed pad The TUSB501DRFR comes in an 8-WFDFN exposed-pad package, also designated as 8-WSON (2 mm x 2 mm). The exposed pad is the thermal and electrical ground connection — it must be soldered to a copper plane on the PCB with a via array under the pad to pull heat away. Without that via stitch, the junction temperature climbs fast if the ambient is near the 85°C limit. The package is surface-mount only, no through-hole option. Decoupling should follow the typical recommendation: a 0.1 µF ceramic within 2 mm of the supply pin, plus a 1 µF bulk cap on the 3.3 V rail. The input and output differential pairs are AC-coupled; the redriver does not pass DC. The signal conditioning is configured via pin strapping — no I2C or SMBus interface, so the equalization and de-emphasis levels are fixed at power-up. ## How it stacks against the TUSB1142RNQR The closest functional sibling is the TUSB1142RNQR, a 10 Gbps redriver that handles USB 3.2 Gen 2. The TUSB501DRFR tops out at 5 Gbps (USB 3.0 Gen 1). The TUSB1142RNQR also has a different temperature grade — 0°C to 70°C commercial range — versus the TUSB501DRFR's -40°C to 85°C industrial range. If your design needs Gen 2 speed and stays in a controlled indoor environment, the TUSB1142RNQR is the speed upgrade. If you need the wider temperature range and Gen 1 is sufficient, the TUSB501DRFR is the correct fit.","metaTitle":"TUSB501DRFR USB 3.0 Redriver, 5 Gbps, 8-WSON","metaDescription":"TI TUSB501DRFR USB 3.0 single-channel redriver with input equalization and output de-emphasis. 5 Gbps data rate, 290 ps delay, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Buffer, ReDriver","Package":"Tape & Reel (TR); Cut Tape (CT)","Delay Time":"290ps","Applications":"USB 3.0","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Data Rate (Max)":"5Gbps","lifecycle_stage":"eol_hot","Current - Supply":"43.8mA","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"1","Capacitance - Input":"1.25 pF","Signal Conditioning":"Input Equalization, Output De-Emphasis","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.49000","currency":"USD"},{"qty":10,"price":"$3.13600","currency":"USD"},{"qty":25,"price":"$2.96440","currency":"USD"},{"qty":100,"price":"$2.56930","currency":"USD"},{"qty":250,"price":"$2.43752","currency":"USD"},{"qty":500,"price":"$2.18718","currency":"USD"},{"qty":1000,"price":"$1.86450","currency":"USD"},{"qty":3000,"price":"$1.86450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ebb3c20d3a3712483fe91b917e4e2b94.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TUSB501DRFR support signal equalization?","answer":"Yes, the TUSB501DRFR includes both input equalization and output de-emphasis.
