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. Integrated pull-up to VIO forces a recessive bus state if the pin is left floating. Referenced to VIO logic levels. |+| 2 | GND | power_in | Device ground reference for both VCC and VIO supplies. |+| 3 | VCC | power_in | 5 V bus-side supply voltage (4.5 V to 5.5 V recommended). Powers the CAN bus driver stage. |+| 4 | RXD | output | CAN receive data output to the CAN controller. Tri-states when device is powered off. Output levels referenced to VIO; IOH = -2 mA, IOL = 2 mA. |+| 5 | VIO | power_in | IO supply voltage for internal level shifter, supporting 1.7 V to 5.5 V logic (1.8 V, 2.5 V, 3.3 V, or 5 V systems). Sets logic thresholds for TXD, RXD, and STB. |+| 6 | CANL | bidirectional | Low-level CAN bus input/output line. Bus fault protected to ±58 V and ISO 7637 pulse tolerant. Connects to the CAN twisted-pair bus. |+| 7 | CANH | bidirectional | High-level CAN bus input/output line. Bus fault protected to ±58 V and ISO 7637 pulse tolerant. Connects to the CAN twisted-pair bus. |+| 8 | STB | input | Standby mode control input. Logic high places the device in low-power standby with wake-up detection; logic low selects normal mode. Integrated pull-up defaults the pin to standby when floating. Referenced to VIO. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSOT-23-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++- `TCAN1044VDDFRDDFR`++## CAD (KiCad official)++- Symbol: `TCAN1044VDDFR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-8`+- 3D model: TSOT-23-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/tcan1044vddfr-datasheet.pdf) (34 pp, sha256 `df71baaa38b56f4c`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
