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 port B1. Connected to common port A when Select = H. Signal range 0 V to VCC; low on-resistance (~7 Ω typ at VCC=4.5 V). |+| 2 | GND | power_in | Ground reference (0 V). Negative analog signal rail; all signal voltages referenced to this pin. |+| 3 | B0 | bidirectional | Analog switch port B0. Connected to common port A when Select = L. Signal range 0 V to VCC; low on-resistance (~7 Ω typ at VCC=4.5 V). |+| 4 | A | bidirectional | Common analog switch port. Routed to B0 (Select=L) or B1 (Select=H). Signal range 0 V to VCC; bidirectional pass-transistor path. |+| 5 | VCC | power_in | Positive supply voltage, 1.65 V to 5.5 V. Sets the maximum analog signal range and digital logic threshold. Bypass with a local 0.1 µF ceramic capacitor to GND. |+| 6 | Select | input | Digital control input selecting the analog signal path: L routes B0↔A, H routes B1↔A. Over-voltage tolerant up to 7 V independent of VCC. Must not be left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-23-6 |+| Category | Comm/UART |+| Pins | 6 |++## Ordering variants++- `SN74LVC1G3157DBVRDBVR`+- `SN74LVC1G3157DBVRDCKR`+- `SN74LVC1G3157DBVRY`++## CAD (KiCad official)++- Symbol: `SN74LVC1G3157DBVR`+- 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:** [Unknown datasheet](docs/sn74lvc1g3157dbvr-datasheet.pdf) (15 pp, sha256 `ad92497e43fe7bbc`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
