sn74lvc2g66dcur.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 -> 8 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

SN74LVC2G66DCUR

Texas Instruments · Analog Switches, Multiplexers · VSSOP-8-0.5mm

SN74LVC2G66DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 1A bidirectional Switch 1 bidirectional analog/digital signal terminal A. Signals up to 5.5 V peak can be passed between 1A and 1B when switch 1 is enabled (1C = H). Rail-to-rail input/output.
2 1B bidirectional Switch 1 bidirectional analog/digital signal terminal B. Signals up to 5.5 V peak can be passed between 1A and 1B when switch 1 is enabled (1C = H).
3 1C input Switch 1 enable control input. L = switch OFF (1A/1B isolated); H = switch ON (1A/1B connected). Referenced to VCC; VIH ≈ VCC × 0.7 at VCC ≥ 2.3 V.
4 GND power_in Ground reference for the device.
5 2A bidirectional Switch 2 bidirectional analog/digital signal terminal A. Signals up to 5.5 V peak can be passed between 2A and 2B when switch 2 is enabled (2C = H).
6 2B bidirectional Switch 2 bidirectional analog/digital signal terminal B. Signals up to 5.5 V peak can be passed between 2A and 2B when switch 2 is enabled (2C = H).
7 2C input Switch 2 enable control input. L = switch OFF (2A/2B isolated); H = switch ON (2A/2B connected).
8 VCC power_in Positive supply input, 1.65 V to 5.5 V. Bypass locally with a 0.1 µF ceramic capacitor to GND.

CAD (KiCad official)

  • Symbol: SN74LVC2G66DCUR
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8-0.5mm (KiCad packages3D, STEP)
  • 3D model files: sn74lvc2g66dcur-etched.step / sn74lvc2g66dcur-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc2g66dcur.step / sn74lvc2g66dcur.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc2g66dcur.step 122 KB You want the bare part, or you mark your own boards.
sn74lvc2g66dcur-etched.step 2.9 MB You want the part with SN74LVC2G66DCUR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 701 faces against 147 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 (29 pp, sha256 dd5515827c66a656, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
