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 | TXD | input | Transmit data input from the CAN controller. A LOW level drives the bus to the dominant state (CANH HIGH, CANL LOW); a HIGH level (or floating) leaves the bus recessive. VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC. |+| 2 | GND | power_in | Ground reference. All device voltages are referenced to pin 2. |+| 3 | VCC | power_in | Supply voltage input. Recommended operating range 4.5 V to 5.5 V; absolute max +7.0 V. Bypass with 100 nF to GND. |+| 4 | RXD | output | Receive data output to the CAN controller. Reports bus state: LOW = dominant, HIGH = recessive. VOH ≥ 0.8·VCC at I4 = -100 µA; VOL ≤ 0.2·VCC at I4 = 1 mA. |+| 5 | Vref | output | Reference voltage output, nominally 0.5·VCC (0.45·VCC to 0.55·VCC with |I5| < 50 µA). Provides a stable mid-supply reference for the CAN controller. |+| 6 | CANL | bidirectional | LOW-level CAN bus line, input/output. Driven LOW (typ 0.5-2.25 V) in dominant state; floats to recessive (~0.5·VCC) otherwise. Withstands -8 V to +18 V and transient voltages -150 V to +100 V. Short-circuit current limited to ~170 mA. |+| 7 | CANH | bidirectional | HIGH-level CAN bus line, input/output. Driven HIGH (typ 2.75-4.5 V) in dominant state; floats to recessive (~0.5·VCC) otherwise. Withstands -8 V to +18 V and transient voltages -150 V to +100 V. Short-circuit current limited to ~-120 mA. |+| 8 | Rs | input | Slope resistor / mode select input. Tie to GND (VRs < 0.3·VCC) for high-speed mode; connect via a resistor to GND (-10 µA < IRs < -200 µA) for slope-controlled mode (rise/fall slope proportional to current out of pin 8); drive HIGH (VRs > 0.75·VCC) for low-current Standby mode where the transmitter is disabled and RXD reports dominant bus activity. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XINLUDA |+| Package | SOP-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `XL82C250`+- `XL82C250XD82C250`++## CAD (KiCad official)++- Symbol: `XL82C250`+- 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:** [XINLUDA datasheet](docs/xl82c250-datasheet.pdf) (11 pp, sha256 `39f6253c66282c1b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
