TCAN1044AVDDFRQ1 from Texas Instruments, in a TSOT-23-8. 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; VIH ≥ 0.7×VIO, VIL ≤ 0.3×VIO; integrated pull-up. |
| 2 | GND | power_in | Ground connection and voltage reference for all measurements. |
| 3 | VCC | power_in | 5V supply voltage; recommended operating range 4.5V to 5.5V. |
| 4 | RXD | tri_state | CAN receive data output; VOH = 0.8×VIO, VOL = 0.2×VIO; tri-stated when device powered off. |
| 5 | VIO | power_in | I/O supply voltage for logic level shifting; 1.7V to 5.5V range supports 1.8V, 2.5V, 3.3V, and 5V logic systems. |
| 6 | CANL | bidirectional | CAN low differential bus line; ±12V common-mode input range, ±58V bus fault protection, 40kΩ to 90kΩ differential input resistance. |
| 7 | CANH | bidirectional | CAN high differential bus line; ±12V common-mode input range, ±58V bus fault protection, ISO 11898-2:2016 compliant. |
| 8 | STB | input | Standby mode control input; high enables low-power standby mode with wake-up detection, low enables normal mode; integrated pull-up. |
