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 of the RS-485 differential receiver (VOH ≥ 2.4V, VOL ≤ 0.4V). High impedance when the receiver is disabled (RE = HIGH). Also drives HIGH under fail-safe when the A/B inputs are open. |+| 2 | /RE | input | Receiver Output Enable, active LOW. Drive LOW to enable RO; drive HIGH to place RO into high impedance (tri-state). Typically tied to DE for automatic direction control in half-duplex RS-485 links. |+| 3 | DE | input | Driver Output Enable, active HIGH. Drive HIGH to enable the differential driver onto pins A/B; drive LOW to tri-state the A/B outputs (>100kΩ). Combined with /RE for half-duplex bus direction control. |+| 4 | DI | input | Driver Input. CMOS-level TX data input to the RS-485 driver (VIL ≤ 0.8V, VIH ≥ 2.0V). When DE is HIGH, a LOW on DI forces A LOW and B HIGH; a HIGH on DI forces A HIGH and B LOW. |+| 5 | GND | power_in | Ground / 0V reference for the device. |+| 6 | A | bidirectional | Non-inverting RS-485 bus line. Serves as the driver's non-inverting output when DE is HIGH and as the receiver's non-inverting input when /RE is LOW. -7V to +12V common-mode range; input impedance ≥ 120kΩ (1/10 unit load). |+| 7 | B | bidirectional | Inverting RS-485 bus line. Serves as the driver's inverting output when DE is HIGH and as the receiver's inverting input when /RE is LOW. -7V to +12V common-mode range; input impedance ≥ 120kΩ (1/10 unit load). |+| 8 | VCC | power_in | Positive supply, +4.75V to +5.25V. Typical supply current 300µA (DE low) to 500µA (DE high), no load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SP485REN-L`+- `SP485REN-L/TR`+- `SP485REN-LSP485RCN-L`+- `SP485REN-LSP485RCN-L/TR`+- `SP485REN-LSP485REP-L`+- `SP485REN-LSP485RCP-L`++## CAD (KiCad official)++- Symbol: `SP485REN-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/sp485ren-l-datasheet.pdf) (9 pp, sha256 `b2e699515e04ebc4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
