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 logic output of the differential receiver. Outputs HIGH (>=2.4V @ Io=-4mA) when A-B > +200mV, LOW (<=0.4V @ Io=+4mA) when A-B < -200mV. High-impedance when /RE is HIGH. |+| 2 | /RE | input | Receiver Output Enable, active LOW. Drive LOW to enable RO; drive HIGH to place RO in high-impedance (three-state). Standard CMOS logic input (VIH >= 2.0V, VIL <= 0.8V). |+| 3 | DE | input | Driver Output Enable, active HIGH. Drive HIGH to enable the differential driver onto A/B; drive LOW to place driver outputs in high-impedance. Standard CMOS logic input (VIH >= 2.0V, VIL <= 0.8V). |+| 4 | DI | input | Driver Input. CMOS logic-level input that drives the differential bus when DE is HIGH. A HIGH on DI forces A > B; a LOW forces B > A. VIH >= 2.0V, VIL <= 0.8V. |+| 5 | GND | power_in | Ground reference for all logic and driver/receiver circuitry. |+| 6 | A | bidirectional | Non-inverting differential driver output / receiver input. Connects to the RS-485/RS-422 bus. Withstands common-mode voltages from -7V to +12V; differential threshold +/-200mV; input resistance >=12kΩ. |+| 7 | B | bidirectional | Inverting differential driver output / receiver input. Connects to the RS-485/RS-422 bus. Withstands common-mode voltages from -7V to +12V; differential threshold +/-200mV; input resistance >=12kΩ. |+| 8 | VCC | power_in | Positive supply input. Operating range +4.75V to +5.25V (+5V nominal). Typical supply current 900µA (SP485). Absolute max +7V. Decouple with a 0.1µF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Logic |+| Pins | 8 |++## Ordering variants++- `SP485EN-L`+- `SP485EN-L/TR`+- `SP485EN-LSP485CN-L`+- `SP485EN-LSP485CN-L/TR`+- `SP485EN-LSP485ES-L`+- `SP485EN-LSP485CS-L`++## CAD (KiCad official)++- Symbol: `SP485EN-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](docs/sp485en-l-datasheet.pdf) (13 pp, sha256 `0ca911ff79c9ea65`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
