TCAN1043ADRQ1 from Texas Instruments, in a SOIC-14. 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 referenced to VIO with integrated 40-80kΩ pull-up resistor |
| 2 | GND | power_in | Ground connection; establish low-impedance return path to PCB ground plane |
| 3 | VCC | power_in | 5V transceiver power supply; requires 100nF bypass capacitor for stable operation |
| 4 | RXD | tri_state | CAN receive data output referenced to VIO; tri-states when VIO falls below UVIO(F) threshold |
| 5 | VIO | power_in | I/O power supply (1.7V to 5.5V range) for digital interface voltage matching; requires 100nF bypass capacitor |
| 6 | EN | input | Mode control enable input with integrated 40-80kΩ pull-down resistor; logic referenced to VIO |
| 7 | INH | tri_state | High-voltage inhibit output sourcing VSUP level; drives system regulator enable pin, open-drain design, sources 6mA maximum |
| 8 | nFAULT | tri_state | Active-low fault status output referenced to VIO; indicates device faults and remote/local wake-up events |
| 9 | WAKE | input | High-voltage local wake-up input (-45V to +45V, limited to VSUP+0.3V maximum); bi-directional edge triggered |
| 10 | VSUP | power_in | High-voltage battery power supply (4.5V to 40V nominal); supports ±58V transients and 300ms load-dump events |
| 11 | NC | unconnected | No connection; internally unconnected, leave floating |
| 12 | CANL | bidirectional | CAN low differential line; I/O pin with ±58V fault tolerance and 25-50kΩ receiver impedance |
| 13 | CANH | bidirectional | CAN high differential line; I/O pin with ±58V fault tolerance and 25-50kΩ receiver impedance |
| 14 | nSTB | input | Standby mode control input with integrated 40-80kΩ pull-down resistor; logic referenced to VIO |
