CAD (KiCad official)

  • Symbol: SN74AHCU04DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: sn74ahcu04dr-etched.step / sn74ahcu04dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ahcu04dr.step / sn74ahcu04dr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahcu04dr.step 195 KB You want the bare part, or you mark your own boards.
sn74ahcu04dr-etched.step 2.5 MB You want the part with SN74AHCU04DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 648 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 (23 pp, sha256 d32bb24afddf475c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
