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 | A | bidirectional | Bidirectional analog/digital switch terminal A. Connected to terminal B when control C is high. Signal amplitude up to 5.5 V(peak), VIO range 0 to VCC. |+| 2 | B | bidirectional | Bidirectional analog/digital switch terminal B. Connected to terminal A when control C is high. Signal amplitude up to 5.5 V(peak), VIO range 0 to VCC. |+| 3 | GND | power_in | Ground reference for the device. All voltages are referenced to this pin. |+| 4 | C | input | Digital control input for the switch. L = switch OFF (A disconnected from B); H = switch ON. VIH threshold ~0.65×VCC to 0.7×VCC depending on VCC; input voltage range 0 to 5.5 V (accepts inputs above VCC). |+| 5 | VCC | power_in | Supply voltage input. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Bypass with a local 0.1 µF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23-5 |+| Category | Comm/UART |+| Pins | 5 |++## Ordering variants++- `SN74LVC1G66DBVRDBVR`+- `SN74LVC1G66DBVRDCKR`+- `SN74LVC1G66DBVRDRLR`+- `SN74LVC1G66DBVRDRYR`+- `SN74LVC1G66DBVRDSFR`+- `SN74LVC1G66DBVRYZPR`++## CAD (KiCad official)++- Symbol: `SN74LVC1G66DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/sn74lvc1g66dbvr-datasheet.pdf) (24 pp, sha256 `673f1c8c93aa0132`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
