  How chip-fetcher pulls CAD from Texas Instruments (ti.com) — the "CAD/Symbols,
  Footprints & 3D Models" widget on a product page (an Ultra Librarian embed) and
  the native STEP. Read before a TI-direct fetch. Trigger words: ti, texas

# Site: Texas Instruments (ti.com)
Top-rung manufacturer source — TI's STEP is authoritative and its ECAD is an Ultra Librarian embed.
## Reach
- `https://www.ti.com/product/<PARTFAMILY>` → the specific orderable (e.g. nRF… no; TI parts like TPS62840). Or `google.com/search?q=<MPN> ti.com cad`.
## Gate
- No login for STEP; the "CAD/Symbols, Footprints & 3D Models" section hands off to **Ultra Librarian** (free login) for the ECAD model → use the `ultralibrarian` site skill from there.
## Download flow
- Product page → **Design & development → CAD/CAE symbols** → STEP downloads directly; ECAD opens the UL flow.
## Catch / When it breaks
- Normalize into `library/<MPN>/`. If the UL embed changes, see the `ultralibrarian` skill. TI occasionally A/B-tests the product page layout — find the CAD section by its heading, not a fixed selector, and publish the fix (`../../CONTRIBUTING.md`).
