74LVC1G66GW

Nexperia · Analog Switches, Multiplexers · SOT-353

74LVC1G66GW from Nexperia, in a SOT-353. 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 Y bidirectional Independent analog switch input or output terminal. Bidirectional analog signal path connected to Z when E is HIGH. Signal voltage must remain between 0 V and VCC.
2 Z bidirectional Independent analog switch output or input terminal. Bidirectional analog signal path connected to Y when E is HIGH. Signal voltage must remain between 0 V and VCC.
3 GND power_in Ground reference (0 V) for the device.
4 E input Digital enable input, active HIGH. When E = HIGH the analog switch is ON (Y-Z connected); when E = LOW the switch is OFF. Schmitt-trigger input, overvoltage tolerant to 5.5 V regardless of VCC.
5 VCC power_in Positive supply voltage, 1.65 V to 5.5 V (absolute max 6.5 V). Sets the maximum switch signal voltage on Y/Z.

CAD (KiCad official)

  • Symbol: 74LVC1G66GW
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SOT-353 (KiCad packages3D, STEP)
  • 3D model files: 74lvc1g66gw-etched.step / 74lvc1g66gw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74lvc1g66gw.step / 74lvc1g66gw.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
74lvc1g66gw.step 87 KB You want the bare part, or you mark your own boards.
74lvc1g66gw-etched.step 1.9 MB You want the part with 74LVC1G66GW already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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: Nexperia datasheet (23 pp, sha256 3da663595b759c8f, 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).
