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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOT-353 |+| Category | Interface |+| Pins | 5 |++## Ordering variants++- `74LVC1G66GWGW`+- `74LVC1G66GWGV`+- `74LVC1G66GWGZ`+- `74LVC1G66GWGM`+- `74LVC1G66GWGN`+- `74LVC1G66GWGS`++## CAD (KiCad official)++- Symbol: `74LVC1G66GW`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SOT-353 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/74LVC1G66GW.pdf) (23 pp, sha256 `3da663595b759c8f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
