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 throw. Connected to COM when IN is logic high. Analog signal range Vss to VDD; on-resistance 0.8Ω typ at Vs=4.5V. |+| 2 | VSS | power_in | Negative supply / ground reference. Typically tied to GND for single-supply operation. |+| 3 | NC | unconnected | No connect. Leave floating or tie as recommended by application; not internally bonded. |+| 4 | COM | passive | Common analog pole of the SPDT switch. Routes to NO when IN=high (break-before-make). Analog signal range Vss to VDD. |+| 5 | VDD | power_in | Positive supply input, +1.8V to +5.5V single-supply operation. Decouple with 0.1μF to VSS. Absolute max VDD-VSS = +7.5V. |+| 6 | IN | input | Digital control input selecting the switch state. TTL/CMOS compatible; VINH ≥ 1.5V (Vs=5V), VINL ≤ 0.55V (Vs=5V). Tolerates drive up to 5.5V independent of VDD. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SC-70-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `GS4157B-CR`+- `GS4157B-CRTR`++## CAD (KiCad official)++- Symbol: `GS4157B-CR`+- 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:** [Gainsil datasheet](docs/gs4157b-cr-datasheet.pdf) (9 pp, sha256 `211dfbbd95b0d179`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
