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 driven from the differential A/B receiver; VOH ≥ 3.5V (IO = -4mA), VOL ≤ 0.4V (IO = 4mA). High-impedance (tri-state) when RE is high. |+| 2 | RE | input | Receiver output enable, active LOW. Drive low to enable the receiver output RO; drive high to place RO in high-impedance state. TTL/CMOS-compatible input (VIH ≥ 2.0V, VIL ≤ 0.8V). |+| 3 | DE | input | Driver output enable, active HIGH. Drive high to enable the differential driver on A/B; drive low to place A/B in high-impedance state. TTL/CMOS-compatible input (VIH ≥ 2.0V, VIL ≤ 0.8V). |+| 4 | DI | input | Driver input. CMOS/TTL logic input that drives the differential A/B outputs when the driver is enabled. VIH ≥ 2.0V, VIL ≤ 0.8V; input current ≤ 10µA. |+| 5 | GND | power_in | Ground reference for the device. Connect to system ground with a low-impedance return. |+| 6 | A | bidirectional | Non-inverting RS-485/RS-422 bus line. Acts as the non-inverting driver output when DE is high and as the non-inverting receiver input when RE is low. Withstands -7V to +12V common-mode range; ±15kV HBM / ±8kV IEC contact ESD protected. |+| 7 | B | bidirectional | Inverting RS-485/RS-422 bus line. Acts as the inverting driver output when DE is high and as the inverting receiver input when RE is low. Withstands -7V to +12V common-mode range; ±15kV HBM / ±8kV IEC contact ESD protected. |+| 8 | VCC | power_in | Positive supply, 4.75V ≤ VCC ≤ 5.25V (nominal 5V). Decouple to GND with a 0.1µF ceramic capacitor placed close to the pin. Absolute maximum 7.0V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SP483EEN-LEEN-L/TR`+- `SP483EEN-LECN-L/TR`++## CAD (KiCad official)++- Symbol: `SP483EEN-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/sp483een-l-datasheet.pdf) (11 pp, sha256 `0d6131874ed6a889`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
