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 that reflects the differential bus state (A-B). High when (A-B) > +200 mV, low when < -200 mV. |+| 2 | /RE | input | Receiver output enable, active low. When low, RO is enabled; when high, RO is high-impedance. |+| 3 | DE | input | Driver output enable, active high. When high, the differential driver outputs A and B are enabled; when low, they are high-impedance. |+| 4 | DI | input | Driver input. CMOS-level logic input to be transmitted differentially onto A/B when DE is high. |+| 5 | GND | power_in | Ground reference (0 V). |+| 6 | A | bidirectional | Non-inverting differential bus I/O. Driver output when DE=H; receiver input when /RE=L. Part of the RS-485 twisted-pair bus. |+| 7 | B | bidirectional | Inverting differential bus I/O. Driver output when DE=H; receiver input when /RE=L. Part of the RS-485 twisted-pair bus. |+| 8 | VCC | power_in | Supply voltage input, 3.0 V to 3.6 V (3.3 V nominal). Bypass to GND with a 0.1 uF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | IKSEMICON |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ILX3485DT`++## CAD (KiCad official)++- Symbol: `ILX3485DT`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [IKSEMICON datasheet](docs/ilx3485dt-datasheet.pdf) (8 pp, sha256 `f7989877c9e5bdc8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
