Low level connects S1 to D; High level connects S2 to D. CMOS logic thresholds referenced to VCC (VIH=2.0V at 3.3V, 2.4V at 5V). |+| 2 | VCC | power_in | Positive supply voltage. Operating range 1.8V to 5.5V (absolute max -0.5V to +7.0V). Quiescent current is 1µA max. |+| 3 | GND | power_in | Ground reference (0V). |+| 4 | S1 | passive | Independent analog switch channel 1. Bidirectional analog signal path connected to D when IN is Low. RON = 4Ω max at VCC=5V; signal range 0 to VCC. |+| 5 | D | passive | Common analog switch pole. Bidirectional pin that connects to either S1 or S2 depending on IN state. |+| 6 | S2 | passive | Independent analog switch channel 2. Bidirectional analog signal path connected to D when IN is High. RON = 4Ω max at VCC=5V; signal range 0 to VCC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-23-6 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `STG719STR`++## CAD (KiCad official)++- Symbol: `STG719STR`+- 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:** [STMicroelectronics datasheet](docs/stg719str-datasheet.pdf) (8 pp, sha256 `e19f35b4d9ed0964`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
