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. When RE is low and (A-B) >= -50mV, RO is high; if (A-B) <= -200mV, RO is low. CMOS-level logic output to the host UART/MCU. |+| 2 | RE | input | Active-low Receiver Output Enable. When RE is low, RO is enabled; when RE is high, RO is high-impedance. RE high together with DE low places the device in low-power shutdown mode. RE is a hot-swap input. |+| 3 | DE | input | Driver Output Enable. When DE is high, the driver outputs (A, B) are enabled; when DE is low, outputs are high-impedance. DE low with RE high enters shutdown mode. DE is a hot-swap input. |+| 4 | DI | input | Driver Input. With DE high, a logic-low DI forces the noninverting output (A) low and the inverting output (B) high; a logic-high DI forces A high and B low. CMOS-level input from the host UART/MCU. |+| 5 | GND | power_in | Ground reference for the device. |+| 6 | A | bidirectional | Noninverting Receiver Input and Noninverting Driver Output (half-duplex bus line A). Connects to the RS-485/RS-422 differential bus; ±15kV HBM ESD-protected. Receiver threshold is -50mV to -200mV vs. B. |+| 7 | B | bidirectional | Inverting Receiver Input and Inverting Driver Output (half-duplex bus line B). Connects to the RS-485/RS-422 differential bus; ±15kV HBM ESD-protected. |+| 8 | VCC | power_in | Positive supply (3.3V nominal, 6.0V absolute maximum). Bypass VCC to GND with a 0.1 µF ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | Logic |+| Pins | 8 |++## Ordering variants++- `SP3072EEN-L`+- `SP3072EEN-L/TR`+- `SP3072EEN-LSP3072EMN-L/TR`+- `SP3072EEN-LSP3071EEN-L`+- `SP3072EEN-LSP3074EEN-L`+- `SP3072EEN-LSP3077EEN-L`+- `SP3072EEN-LSP3070EEN-L`+- `SP3072EEN-LSP3073EEN-L/TR`+- `SP3072EEN-LSP3076EEN-L`++## CAD (KiCad official)++- Symbol: `SP3072EEN-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/sp3072een-l-datasheet.pdf) (26 pp, sha256 `24efa6b28f4cec32`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
