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 | RO | output | Receiver output. Drives logic level derived from the A-B differential input; high-Z when /RE is high. Fail-safe forces RO high when A/B are open or shorted. |+| 2 | /RE | input | Receiver output enable, active low. RO is enabled when /RE is low; RO is high-Z when /RE is high. With DE=0 and /RE=1 the device enters shutdown. |+| 3 | DE | input | Driver output enable, active high. Driver outputs A/B are enabled when DE is high; outputs are high-Z when DE is low. With DE=0 and /RE=1 the device enters shutdown. |+| 4 | DI | input | Driver input. Logic level to be transmitted onto the differential A/B bus when the driver is enabled. VIH=2.0 V min, VIL=0.8 V max, 100 mV typ hysteresis. |+| 5 | GND | power_in | Ground reference for logic and bus signals. |+| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output (RS-485 bus line A). Withstands ±13 V bus voltage; ±15 kV IEC 61000-4-2 contact-discharge ESD protected. |+| 7 | B | bidirectional | Inverting receiver input and inverting driver output (RS-485 bus line B). Withstands ±13 V bus voltage; ±15 kV IEC 61000-4-2 contact-discharge ESD protected. |+| 8 | VCC | power_in | Supply voltage. Operates from +3.0-3.6 V or +4.5-5.5 V. Absolute maximum +7 V. Typical ICC 270-350 µA; shutdown ISHDN 10 µA max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOP-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++- `BL3085I47`++## CAD (KiCad official)++- Symbol: `BL3085`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Unknown datasheet](docs/bl3085-datasheet.pdf) (10 pp, sha256 `52853b49ab796e41`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
