TCAN1044DRQ1 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 from the CAN controller/MCU. Internal pull-up to VCC (or VIO on devices with VIO). Drives the CAN bus low (dominant) when logic low. |
| 2 | GND | power_in | Device ground connection (0 V reference). |
| 3 | VCC | power_in | 5-V main supply voltage for the CAN transceiver. Recommended operating range 4.5 V to 5.5 V (nom 5 V). |
| 4 | RXD | output | CAN receive data output to the CAN controller/MCU. High-impedance (tri-state) when unpowered. Output high/low current rated ±2 mA. |
| 5 | NC/VIO | unconnected | On the TCAN1044-Q1 (no VIO): No Connect, not internally bonded. On the TCAN1044V-Q1 variant: VIO supply (1.7 V to 5.5 V) for the digital I/O level shifter of TXD/RXD/STB. The TCAN1044DRQ1 orderable is the non-VIO device; treat this pin as NC. |
| 6 | CANL | bidirectional | Low-level CAN bus I/O line. Connects to the CAN bus with CANH through a 60 Ω termination network. Tolerates ±58 V bus fault voltage. |
| 7 | CANH | bidirectional | High-level CAN bus I/O line. Connects to the CAN bus with CANL through a 60 Ω termination network. Tolerates ±58 V bus fault voltage. |
| 8 | STB | input | Standby mode control input with integrated pull-up. High = low-power standby mode with bus wake-up support; low = normal (active) mode. |
