XL1040 from XINLUDA, in a SOIC-8. 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. Logic-low drives the bus dominant; logic-high (or float) leaves the bus recessive. Input thresholds VIL ≤ 0.8 V, VIH ≥ 2 V (relative to VCC). A dominant time-out (~4 ms typ) prevents a stuck-low TXD from permanently holding the bus dominant. |
| 2 | GND | power_in | Ground / power supply return. |
| 3 | VCC | power_in | Supply voltage input, VCC = 5 V ± 10% (absolute max -0.3 V to +6 V). Decouple close to the pin. |
| 4 | RXD | output | Receive data output to the CAN controller; reflects the state of the differential bus. Drives high (VOH ≥ 4 V at IO = -2 mA) for recessive and low (VOL ≤ 0.4 V at IO = 2 mA) for dominant. |
| 5 | SPLIT | output | Common-mode stabilization output, nominally VCC/2 (~2.5 V, range 2-3 V). Typically connected to the midpoint of a split-termination network to stabilize the bus common-mode voltage and improve EMC. |
| 6 | CANL | bidirectional | Low-level CAN bus line (differential). Dominant output ≈ 1.5 V; recessive ≈ 2.5 V. Withstands bus-side voltages of -27 V to +40 V and transient events per automotive requirements. |
| 7 | CANH | bidirectional | High-level CAN bus line (differential). Dominant output ≈ 3.5 V; recessive ≈ 2.5 V. Withstands bus-side voltages of -27 V to +40 V and transient events per automotive requirements. |
| 8 | STB | input | Mode select input. Low = high-speed (normal) mode; high (or float) = standby mode with remote wake-up via the bus. In standby the device draws only ~10 µA typical. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 340 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
