Files

  • sn74lvc2t45dctr.kicad_mod footprint (KiCad)
  • sn74lvc2t45dctr.kicad_sym symbol (KiCad)
  • sn74lvc2t45dctr.step 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
  • sn74lvc2t45dctr.lbr Fusion / EAGLE library part (adom-lbr from the files above with this page's metadata; no embedded 3D, bind the STEP)

Provenance

  • sn74lvc2t45dctr.kicad_mod: KiCad Package_SO:SSOP-8_2.95x2.8mm_P0.65mm footprint (https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Package_SO.pretty/SSOP-8_2.95x2.8mm_P0.65mm.kicad_mod), unmodified except the 3D model path (now sn74lvc2t45dctr.step). sha256/16 of the original: 8b77f3d670a43e2d.
  • sn74lvc2t45dctr.step: KiCad Package_SO.3dshapes/SSOP-8_2.95x2.8mm_P0.65mm.step (packages3D), byte-identical copy (sha256/16 9b95dcfed5f8335a). The footprint's (model (offset 0 0 0) (rotate 0 0 0)), so the STEP is already in the footprint frame and no transform was applied. Checked with OpenCascade (step2glb features): Z-up, seated on the board plane, origin = footprint origin.
  • Upstream terms: KiCad official library (gitlab.com/kicad/libraries/kicad-footprints, kicad-packages3D and kicad-symbols, master, fetched 2026-11-02). License: CC-BY-SA 4.0 with the KiCad libraries exception (using these files in a design, and distributing the design or its manufacturing output, does not require the design to be licensed under CC-BY-SA). The STEP is KiCad's generic body for this package, not a manufacturer model.
  • sn74lvc2t45dctr.kicad_sym: KiCad Logic_LevelTranslator:SN74LVC2T45DCUR (https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master/Logic_LevelTranslator.kicad_symdir/SN74LVC2T45DCUR.kicad_sym). KiCad has no DCT-package symbol; the DCU symbol has the same pinout (TI SCES516N Table 4-1 "Pin Functions: DCT, DCU": 1 VCCA, 2 A1, 3 A2, 4 GND, 5 DIR, 6 B2, 7 B1, 8 VCCB). Renamed to the MPN; pins unchanged.

Notes

  • Land pattern check against TI DCT0008A (pins_digest.md: 8X 1.1 x 0.4 mm pads, 3.8 mm between pad rows, read here as pad-centre to pad-centre as TI draws its land patterns): KiCad pads are 1.6 x 0.3 mm at x = +/-1.7 mm, so the outer (toe) pad edge is at 2.50 mm against TI 2.45 mm, but the KiCad pads reach 0.45 mm further inward (heel edge 0.9 vs 1.35 mm) and are 0.1 mm narrower. Pitch 0.65 mm and body 2.95 x 2.8 mm match. Usable as is; switch to TI's land pattern if the assembler wants an exact IPC match.
