Texas Instruments · CAN Transceivers · SOT-23-8
TCAN334DCNR from Texas Instruments, in a SOT-23-8. 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 and HIGH for recessive bus states; integrated pull-up resistor. |
| 2 | GND | power_in | Ground connection (0V reference). |
| 3 | VCC | power_in | 3.3V supply voltage input. |
| 4 | RXD | tri_state | CAN receive data output; LOW for dominant and HIGH for recessive bus states; tri-state. |
| 5 | SHDN | input | Shutdown mode control input; drive HIGH to enable shutdown mode; internal pull-down biases to LOW for normal operation. |
| 6 | CANL | bidirectional | Low-level CAN bus line; bidirectional driver/receiver with ±12V common-mode range and ±14V overvoltage protection. |
| 7 | CANH | bidirectional | High-level CAN bus line; bidirectional driver/receiver with ±12V common-mode range and ±14V overvoltage protection. |
| 8 | STB | input | Standby mode control input; drive HIGH to enable low-power standby with wake capability; integrated pull-down biases to LOW for normal operation. |
