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 the digital control input IN is logic high (1). Handles analog or digital signals from 0V to V+ with ~4.5Ω typical on-resistance; continuous current limit ±300mA. |+| 2 | GND | power_in | Ground reference for the device. Absolute maximum V+/IN to GND rating is -0.3V to 7.0V. |+| 3 | NC | bidirectional | Normally-Closed analog switch terminal. Connected to COM when the digital control input IN is logic low (0). Analog signal range 0V to V+, ~4.5Ω typical on-resistance; continuous current limit ±300mA. |+| 4 | COM | bidirectional | Common analog switch terminal. Routed to either NO or NC depending on the state of the IN control pin, with break-before-make switching (~5ns tBBM at 5V). Analog signal range 0V to V+; continuous current ±300mA. |+| 5 | V+ | power_in | Positive power supply. Operating range 1.8V to 5.5V. Absolute maximum 7.0V referenced to GND. Quiescent supply current typically <1µA. |+| 6 | IN | input | Digital control input (TTL/CMOS compatible) that selects the switch path. Logic 1 connects NO↔COM (NC open); logic 0 connects NC↔COM (NO open). VIH ≥ 1.5V at V+=5V (≥1.3V at 3.3V); VIL ≤ 0.6V at V+=5V (≤0.5V at 3.3V). Input leakage ≤1µA. Must not be left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOT-23-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `RS2057XH`+- `RS2057XHRS2057XC6`++## CAD (KiCad official)++- Symbol: `RS2057XH`+- 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:** [Jiangsu RUNIC Tech datasheet](docs/rs2057xh-datasheet.pdf) (11 pp, sha256 `c1747b824cf512bb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
