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. Reflects the state of the differential receiver input (A-B): HIGH when A-B > +0.2V, LOW when A-B < -0.2V. High-impedance (tri-state) when RE is HIGH. Fail-safe HIGH when inputs are open. |+| 2 | RE | input | Receiver output enable, active LOW. A logic LOW enables the receiver output RO; a logic HIGH tri-states RO. VIH ≥ 2.0V, VIL ≤ 0.8V. |+| 3 | DE | input | Driver output enable, active HIGH. A logic HIGH enables the differential driver outputs A and B; a logic LOW tri-states the driver outputs. VIH ≥ 2.0V, VIL ≤ 0.8V. |+| 4 | DI | input | Driver input. TTL/CMOS logic input driving the differential bus outputs when DE is HIGH: DI=HIGH drives A HIGH and B LOW; DI=LOW drives A LOW and B HIGH. VIH ≥ 2.0V, VIL ≤ 0.8V. |+| 5 | GND | power_in | Ground reference (0V) for the device. |+| 6 | A | bidirectional | Non-inverting driver output / receiver input. Connects to the RS-485/RS-422 differential bus line A. Common-mode range -7V to +12V; withstands ±15kV HBM and ±15kV IEC61000-4-2 Air Discharge ESD. |+| 7 | B | bidirectional | Inverting driver output / receiver input. Connects to the RS-485/RS-422 differential bus line B. Common-mode range -7V to +12V; withstands ±15kV HBM and ±15kV IEC61000-4-2 Air Discharge ESD. |+| 8 | VCC | power_in | Positive supply voltage. Operating range 4.75V to 5.25V (5V nominal). Typical supply current 900µA (no load, driver enabled). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SP485EEN-L`+- `SP485EEN-L/TR`+- `SP485EEN-LSP485ECN-L`+- `SP485EEN-LSP485ECN-L/TR`+- `SP485EEN-LSP485EMN-L/TR`+- `SP485EEN-LSP481ECN-L/TR`+- `SP485EEN-LSP481EEN-L/TR`++## CAD (KiCad official)++- Symbol: `SP485EEN-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/a7439ffd550f8e2a4300e062e08e4c62.pdf) (9 pp, sha256 `4a2a188692170b46`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
