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 is logic high; bidirectional analog signal path, may be an input or output. Signal range 0V to V+. |+| 2 | GND | power_in | Ground reference for the device. |+| 3 | NC | bidirectional | Normally-Closed analog switch terminal. Connected to COM when IN is logic low; bidirectional analog signal path, may be an input or output. Signal range 0V to V+. |+| 4 | COM | bidirectional | Common analog switch terminal. Routed to either NO or NC based on the IN logic level; bidirectional signal path with 4.5Ω typical on-resistance at V+ = 5.0V. |+| 5 | V+ | power_in | Positive power supply input. Operating range 1.8V to 5.5V; typical supply current 5µA max at V+ = 5.5V. Bypass with 0.1µF to GND. |+| 6 | IN | input | Digital control input selecting which switch terminal (NO or NC) connects to COM. TTL/CMOS compatible: VIH ≥ 1.5V (min at V+=4.5-5.5V), VIL ≤ 0.6V. Logic 1 closes COM-NO; logic 0 closes COM-NC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SGMICRO |+| Package | SC-70-6(SOT-363) |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `SGM3157YC6/TR`++## CAD (KiCad official)++- Symbol: `SGM3157YC6`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6(SOT-363) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SGMICRO datasheet](docs/sgm3157yc6-datasheet.pdf) (11 pp, sha256 `da0e41efe044bdc7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
