sn74lvc1g04dckr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

SN74LVC1G04DCKR

UMW · Inverters · SC-70-5

SN74LVC1G04DCKR from UMW, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection. Empty foot with no internal die bond; leave floating or tie to a static net per board convention.
2 A input Logic input to the inverter. CMOS-compatible thresholds scale with VCC (VIH ≈ 0.7·VCC, VIL ≈ 0.3·VCC at VCC = 3-5.5 V). Input leakage typically 0.1 µA, absolute max ±5.5 V regardless of VCC.
3 GND power_in Device ground / 0 V reference for the logic and output stages.
4 Y output Inverted logic output (Y = /A). Push-pull CMOS drive rated up to ±32 mA at VCC = 4.5 V (±16 mA at 3 V, ±8 mA at 2.3 V, ±4 mA at 1.65 V). Swings rail-to-rail into a light load.
5 VCC power_in Positive supply, 1.65 V to 5.5 V operating (6.5 V absolute max). Bypass with a local 0.1 µF ceramic to GND. Static ICC ~0.1 µA typical.

CAD (KiCad official)

  • Symbol: SN74LVC1G04DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: sn74lvc1g04dckr-etched.step / sn74lvc1g04dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc1g04dckr.step / sn74lvc1g04dckr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g04dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74lvc1g04dckr-etched.step 2.4 MB You want the part with SN74LVC1G04DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 601 faces against 102 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: UMW datasheet (15 pp, sha256 900ca612376ee7ff, retrieved 2026-08-17, tier: lcsc)
  • 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).
