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 | NO | passive | Normally Open switch terminal. Connected to COM when IN is HIGH; disconnected (high impedance) when IN is LOW. Bidirectional analog signal path, 0V to VCC, ~4.5Ω typ. ON-resistance at VCC=5V. |+| 2 | GND | power_in | Ground reference for the device (0V). |+| 3 | NC | passive | Normally Closed switch terminal. Connected to COM when IN is LOW; disconnected (high impedance) when IN is HIGH. Bidirectional analog signal path, 0V to VCC, ~4.5Ω typ. ON-resistance at VCC=5V. Note: 'NC' here means Normally Closed switch pole, not No-Connect. |+| 4 | COM | passive | Common switch terminal (pole). Routed to either NO or NC depending on the IN control state. Bidirectional analog signal path, 0V to VCC. |+| 5 | VCC | power_in | Positive supply voltage, 1.65V to 5.5V (absolute max 6.0V). Typical ICC = 5 μA at 5.5V. |+| 6 | IN | input | Digital control input selecting the switch path. IN=0 connects COM to NC (NO off); IN=1 connects COM to NO (NC off). Must be driven HIGH or LOW; VIH=2.6V (5V supply), VIL=0.8V (5V supply). TTL/CMOS compatible. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOT-23-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `COSN74LVC1G3157DBVR`+- `COSN74LVC1G3157DBVRDCKR`++## CAD (KiCad official)++- Symbol: `COSN74LVC1G3157DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cosn74lvc1g3157dbvr-datasheet.pdf) (10 pp, sha256 `8abc30c2fd2ebf05`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
