Pin-Tabelle8
| Pin | Signal / Name | Typ | Alternative Funktionen |
|---|---|---|---|
| 1 | TXD | Digital | CAN TX Data Input — from MCU CAN controller; LOW drives bus dominant; HIGH = recessive; 3.3V/5V logic compatible |
| 2 | GND | Ground | System Ground (0V) |
| 3 | VCC | Power | Positive Power Supply (+4.5V to +5.5V DC); add 100nF bypass cap to GND near pin |
| 4 | RXD | Digital | CAN RX Data Output — to MCU CAN controller; LOW = bus dominant; HIGH = recessive; push-pull output |
| 5 | NC | NC | - |
| 6 | CANL | Digital | CAN Bus Low — differential bus line; dominant = 1.5V, recessive = 2.5V; terminate with 120Ω between CANH and CANL at each end |
| 7 | CANH | Digital | CAN Bus High — differential bus line; dominant = 3.5V, recessive = 2.5V; terminate with 120Ω between CANH and CANL at each end |
| 8 | S | Digital | Silent Mode Select — LOW: normal operation; HIGH: silent mode (TXD disabled, RXD still active, no bus disturbance); tie LOW if not needed |
