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 | VCC1 | power_in | Digital-side (side 1) supply voltage. Operating range 1.71 V to 5.5 V (1.8 V, 2.5 V, 3.3 V, or 5 V logic). Bypass locally to GND1. |+| 2 | TXD | input | CAN transmit data input from the host controller. LOW drives a dominant bus state, HIGH allows a recessive bus state. Referenced to VCC1/GND1 logic levels. |+| 3 | RXD | output | CAN receive data output to the host controller. LOW indicates dominant bus state, HIGH indicates recessive bus state. Output current limited to ±15 mA (absolute max). |+| 4 | GND1 | power_in | Digital-side (side 1) ground reference for VCC1, TXD, and RXD. |+| 5 | GND2 | power_in | Transceiver-side (side 2) ground reference for VCC2, CANH, and CANL. Isolated from GND1 by the 5000 Vrms SiO2 barrier. |+| 6 | CANL | bidirectional | Low-level CAN bus line. Withstands ±70 V DC bus fault and ±16 kV HBM ESD to GND2. Tolerates -70 V to 70 V bus voltage and -70 V to 70 V differential (absolute max). |+| 7 | CANH | bidirectional | High-level CAN bus line. Withstands ±70 V DC bus fault and ±16 kV HBM ESD to GND2. Tolerates -70 V to 70 V bus voltage and -70 V to 70 V differential (absolute max). |+| 8 | VCC2 | power_in | Transceiver-side (side 2) supply voltage. Operating range 4.5 V to 5.5 V.
