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 analog switch terminal. When the logic control (IN) is high, NO is connected to COM through the ~0.6 Ω on-resistance channel; when IN is low, NO is disconnected. Signal range 0 V to V+. |+| 2 | GND | power_in | Ground reference for the device. Must be tied to the system ground. |+| 3 | NC | passive | Normally-Closed analog switch terminal. When the logic control (IN) is low, NC is connected to COM through the ~0.6 Ω on-resistance channel; when IN is high, NC is disconnected. Signal range 0 V to V+. |+| 4 | COM | passive | Common analog switch terminal. Routed to either NO or NC depending on the IN logic state (break-before-make). Signal range 0 V to V+, continuous current ±500 mA max. |+| 5 | V+ | power_in | Positive supply input. Operating range +1.8 V to +5.5 V; absolute max 7.0 V referenced to GND. Quiescent supply current ≤1 µA. |+| 6 | IN | input | Digital control input, TTL/CMOS compatible. VIH ≥ 1.5 V (@5 V) / 1.3 V (@3.3 V); VIL ≤ 0.6 V (@5 V) / 0.5 V (@3.3 V). Logic 0 → NC on / NO off; Logic 1 → NO on / NC off. Must not be left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SC-70-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `RS2257XC6`+- `RS2257XC6RS2257XH`++## CAD (KiCad official)++- Symbol: `RS2257XC6`+- 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:** [Jiangsu RUNIC Tech datasheet](docs/rs2257xc6-datasheet.pdf) (11 pp, sha256 `2518049fa2c22b06`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
