TCAN337GDR 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, HIGH for recessive bus states) with integrated pull-up (VIH ≥ 2V, VIL ≤ 0.8V). |
| 2 | GND | power_in | Ground connection for the device. |
| 3 | VCC | power_in | 3.3V supply voltage with operating range 3.0V to 3.6V. |
| 4 | RXD | tri_state | CAN receive data tri-state output (LOW for dominant, HIGH for recessive, VOH = 0.8×VCC, VOL = 0.2V to 0.4V). |
| 5 | FAULT | output | Open-drain fault output driven low on TXD dominant timeout, RXD dominant timeout, thermal shutdown, or undervoltage lockout (ICL = 4-12mA at 0.4V). |
| 6 | CANL | bidirectional | Low level CAN bus line bidirectional with ±14V bus fault protection and common mode range ±12V (normal/silent modes). |
| 7 | CANH | bidirectional | High level CAN bus line bidirectional with ±14V bus fault protection and common mode range ±12V (normal/silent modes). |
| 8 | S | input | Silent mode input (drive HIGH for silent mode with driver disabled) with integrated pull-down (VIH ≥ 2V, VIL ≤ 0.8V). |
