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 | bidirectional | Normally-Open analog switch terminal. Connected to COM when IN = logic high. Rail-to-rail analog signal range 0 V to V+. On-resistance 0.8Ω typ, continuous current ±150mA (peak ±250mA). |+| 2 | GND | power_in | Ground reference (0V) for the device. |+| 3 | NC | bidirectional | Normally-Closed analog switch terminal. Connected to COM when IN = logic low. Rail-to-rail analog signal range 0 V to V+. On-resistance 0.8Ω typ, continuous current ±150mA (peak ±250mA). |+| 4 | COM | bidirectional | Common analog switch terminal. Routed to either NO or NC based on the state of the IN control pin. Rail-to-rail signal range 0 V to V+. |+| 5 | V+ | power_in | Positive power supply input. Operating range 1.8V to 5.5V; absolute max 6V. Quiescent supply current 0.1µA typ. |+| 6 | IN | input | Digital control input that selects which switch terminal is connected to COM (IN=0 selects NC, IN=1 selects NO). TTL/CMOS compatible: VIH ≥ 1.6V, VIL ≤ 0.4V at V+=4.5V. Input tolerates drive signals up to 5.5V independent of supply voltage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SGMICRO |+| Package | SC-70-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `SGM4157YC6/TR`++## CAD (KiCad official)++- Symbol: `SGM4157YC6`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SGMICRO datasheet](docs/sgm4157yc6-datasheet.pdf) (11 pp, sha256 `20b74037b24c2934`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
