TCAN1042HDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TXD | input | CAN transmit data input; LOW for dominant state and HIGH for recessive bus state. |
| 2 | GND | power_in | Ground connection; can be connected to thermal pad in VSON package for thermal optimization. |
| 3 | VCC | power_in | Transceiver 5-V supply voltage with recommended operating range 4.5 to 5.5 V. |
| 4 | RXD | output | CAN receive data output; LOW for dominant state and HIGH for recessive bus state or wake-up events. |
| 5 | NC | unconnected | No internal connection; left floating or tied to any convenient net. |
| 6 | CANL | bidirectional | Low level CAN bus input/output line with ±70 V bus fault protection and differential input impedance ≥30 kΩ. |
| 7 | CANH | bidirectional | High level CAN bus input/output line with ±70 V bus fault protection and differential input impedance ≥30 kΩ. |
| 8 | STB | input | Standby Mode control input (active HIGH); enables low-power standby with remote wake-up capability. |
