| 2 | GND | power_in | Ground connection |
| 3 | VCC | power_in | Transceiver 5V supply voltage with voltage range -0.3V to 7V |
| 4 | RXD | output | CAN receive data output (LOW for dominant, HIGH for recessive) with voltage range -0.3V to +7V and VI ≤ VIO + 0.3V |
| 5 | VIO | power_in | I/O level shifting supply voltage for V-suffix devices with voltage range -0.3V to 7V |
| 6 | CANL | bidirectional | Low level CAN bus input/output line with voltage range -58V to 58V |
| 7 | CANH | bidirectional | High level CAN bus input/output line with voltage range -58V to 58V |
| 8 | S | input | Silent mode control input (active high) with voltage range -0.3V to +7V and VI ≤ VIO + 0.3V |
