3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74act14dr.step 195 KB You want the bare part, or you mark your own boards.
sn74act14dr-etched.step 2.1 MB You want the part with SN74ACT14DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 563 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (40 pp, sha256 f4f062bd1e9c6ceb, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
