TCAN1051HDR from Texas Instruments, 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 | CAN transmit data input from the MCU. LOW drives the bus dominant; HIGH lets the bus recess. Internal pull-up to VCC. |
| 2 | GND | power_in | Device ground reference (0 V). |
| 3 | VCC | power_in | Transceiver 5-V supply voltage (nominal 4.5-5.5 V). Bypass with a 100 nF ceramic to GND close to the pin. |
| 4 | RXD | output | CAN receive data output to the MCU. LOW when the bus is dominant, HIGH when the bus is recessive. Driven to VCC on non-'V' variants. |
| 5 | NC | unconnected | No connect. On non-'V' suffix variants (including TCAN1051H) pin 5 is unused and should be left floating or tied to GND. |
| 6 | CANL | bidirectional | Low-side CAN bus I/O line. Differential pair with CANH. ±70 V bus fault protection and ±30 V common-mode range on H variants. |
| 7 | CANH | bidirectional | High-side CAN bus I/O line. Differential pair with CANL. ±70 V bus fault protection and ±30 V common-mode range on H variants. |
| 8 | S | input | Silent (listen-only) mode control input, active HIGH. Tie LOW (or to GND) for normal transmit/receive operation; drive HIGH to disable the transmitter and remain a passive bus listener. |
