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. CMOS-level output driven from the differential A/B receiver. High-Z when the receiver is disabled (RE=HIGH). Fail-safe HIGH when receiver inputs are open. |+| 2 | RE | input | Receiver Output Enable, active LOW. A logic LOW enables the differential receiver (RO driven); a logic HIGH tri-states RO. Input high/low thresholds: VIH=2.0V min, VIL=0.8V max. |+| 3 | DE | input | Driver Output Enable, active HIGH. A logic HIGH enables the differential driver outputs on A/B; a logic LOW tri-states them. VIH=2.0V min, VIL=0.8V max. |+| 4 | DI | input | Driver Input. CMOS-level logic input whose state controls the differential driver output on A/B when DE is HIGH. VIH=2.0V min, VIL=0.8V max, IIN=±10 µA. |+| 5 | GND | power_in | Ground reference (0 V) for the device. |+| 6 | A | bidirectional | Non-inverting driver output / non-inverting receiver input on the RS-485/RS-422 differential bus. Common-mode range -7V to +12V; short-circuit protected to ±250 mA. |+| 7 | B | bidirectional | Inverting driver output / inverting receiver input on the RS-485/RS-422 differential bus. Common-mode range -7V to +12V; short-circuit protected to ±250 mA. |+| 8 | VCC | power_in | Positive supply, +3.3V ±5%. Absolute maximum +6.0V. Typical supply current 1000 µA (driver enabled, no load). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SP3485EN-LCN-L`+- `SP3485EN-LCN-L/TR`+- `SP3485EN-LEN-L`+- `SP3485EN-LEN-L/TR`++## CAD (KiCad official)++- Symbol: `SP3485EN-L`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MaxLinear datasheet](https://datasheet.lcsc.com/datasheet/pdf/621d20e6d635fc4ea92a536db4271ee0.pdf) (9 pp, sha256 `b01eb091aab969e3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
