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 | B1 | bidirectional | Analog switch data port B1. Passes through to A when Select is high. Analog signal range 0 to VCC; on-resistance typ 3-17Ω depending on VCC. |+| 2 | GND | power_in | Ground / substrate reference (Land). |+| 3 | B0 | bidirectional | Analog switch data port B0. Passes through to A when Select is low. Analog signal range 0 to VCC. |+| 4 | A | bidirectional | Common analog switch port A. Connects to B0 (Select=L) or B1 (Select=H). Bidirectional analog signal path. |+| 5 | VCC | power_in | Positive supply, 1.65V to 5.5V operating (absolute max 7V). Sets the analog signal range and logic thresholds. |+| 6 | Select | input | Digital channel-select input with over-voltage tolerance up to 7V (may exceed VCC). L = route B0→A, H = route B1→A. Must not be left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SC-70-6 |+| Category | Interface |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `ET3157`+- 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:** [Unknown datasheet](docs/et3157-datasheet.pdf) (13 pp, sha256 `3aefe2b48b982b83`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
