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 receiver is enabled (RE low): if V(A)-V(B) > -50mV, RO outputs high; if V(A)-V(B) < -200mV, RO outputs low. High-impedance when receiver disabled. |+| 2 | RE | input | Receiver output enable (active-low). When RE is low, RO is enabled. When RE is high, receiver is disabled. With RE high and DE low, the chip enters shutdown state. |+| 3 | DE | input | Driver output enable (active-high). When DE is high, the driver outputs are enabled. When DE is low, the driver outputs go high-impedance. With RE high and DE low, the chip enters shutdown state. |+| 4 | DI | input | Driver input. When DI is low, non-inverting output (A) is forced low and inverting output (B) is forced high. When DI is high, A is high and B is low. |+| 5 | GND | power_in | Ground reference (0V). |+| 6 | A | bidirectional | RS-485/RS-422 bus interface pin. Driver non-inverting output and receiver non-inverting input. Bus voltage range -8V to +13V; ±15kV HBM ESD protection. |+| 7 | B | bidirectional | RS-485/RS-422 bus interface pin. Driver inverting output and receiver inverting input. Bus voltage range -8V to +13V; ±15kV HBM ESD protection. |+| 8 | VCC | power_in | Positive supply, 4.75V to 5.25V (typ 5V). Bypass with a 0.1µF ceramic capacitor to GND. Absolute maximum 7V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GEC EESA |+| Package | MSOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `WS3080`++## CAD (KiCad official)++- Symbol: `WS3080`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GEC EESA datasheet](docs/ws3080-datasheet.pdf) (12 pp, sha256 `5c073075993893c6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
