TCAN337DR 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 with 2V HIGH and 0.8V LOW thresholds, integrated pull-up, LOW drives dominant bus state |
| 2 | GND | power_in | Ground connection and 0V system reference |
| 3 | VCC | power_in | 3.3V positive supply voltage, 3.0V to 3.6V nominal operating range |
| 4 | RXD | tri_state | CAN receive data output (tri-state), 0.2-0.4V LOW for dominant, 0.8×VCC HIGH for recessive bus state |
| 5 | FAULT | output | Open-drain fault output pin, driven low on TXD DTO, RXD DTO, thermal shutdown, or UV lockout, 4-12mA sink at 0.4V |
| 6 | CANL | bidirectional | Low-level CAN bus line (differential pair with CANH), ±14V surge protection, 60Ω characteristic impedance |
| 7 | CANH | bidirectional | High-level CAN bus line (differential pair with CANL), ±14V surge protection, 60Ω characteristic impedance |
| 8 | S | input | Silent mode control, drive HIGH for receive-only mode with driver disabled, LOW for normal bidirectional mode, integrated pull-down |
