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 HIGH (>= VCC-0.4V, IO=-1.5mA) when A-B > +200mV, LOW (<= 0.4V, IO=2.5mA) when A-B < -200mV. Fail-safe HIGH when receiver inputs are open. Enters high-impedance when RE is HIGH. |+| 2 | RE | input | Receiver Output Enable, active LOW. Logic LOW enables the receiver output (RO); logic HIGH tri-states RO. Combined with DE=LOW puts the device into shutdown mode. |+| 3 | DE | input | Driver Output Enable, active HIGH. Logic HIGH enables the differential driver outputs on A and B; logic LOW forces A/B into high-impedance. VIH >= 2.0V, VIL <= 0.8V, input current +/-10 uA. |+| 4 | DI | input | Driver data input. When DE is HIGH, DI=HIGH drives A HIGH / B LOW and DI=LOW drives A LOW / B HIGH. VIH >= 2.0V, VIL <= 0.8V, input current +/-10 uA. |+| 5 | GND | power_in | Ground reference for the device. Connect to system ground. |+| 6 | A | bidirectional | Non-inverting driver output / non-inverting receiver input on the RS-485 differential bus. Common-mode input range -7V to +12V; receiver input resistance 12 kOhm min (15 kOhm typ). Driver short-circuit current limited to +/-250 mA. |+| 7 | B | bidirectional | Inverting driver output / inverting receiver input on the RS-485 differential bus. Common-mode input range -7V to +12V; receiver input resistance 12 kOhm min (15 kOhm typ). Driver short-circuit current limited to +/-250 mA. |+| 8 | VCC | power_in | Positive supply input, 3.3V +/-5% (absolute max 6.0V). Typical supply current 800-1000 uA (no load); ~1 uA typ / 10 uA max in shutdown. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SP3483EN-L`+- `SP3483EN-L/TR`+- `SP3483EN-LSP3483CN-L`+- `SP3483EN-LSP3483CN-L/TR`++## CAD (KiCad official)++- Symbol: `SP3483EN-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/sp3483en-l-datasheet.pdf) (9 pp, sha256 `bf5d68b5683ccead`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
