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 MCU. Low drives a dominant bus state; high (or floating with internal pull-up) leaves the bus recessive. |+| 2 | GND | power_in | Ground return. The exposed thermal pad on the DMT (VSON) variant must also be soldered to GND. |+| 3 | VCC | power_in | 5V supply for the CAN bus transceiver core. Nominal 4.5V-5.5V per recommended operating conditions. |+| 4 | RXD | output | CAN receive data output to the MCU. Tri-state; low = dominant bus, high = recessive bus. |+| 5 | VIO | power_in | Digital I/O rail for level shifting to the MCU. Supports 1.8V-5V to match the host processor's I/O voltage. |+| 6 | nINT/SDO | output | Muxed digital output. Acts as SPI serial-data-out (SDO) while nCS is low; becomes the active-low interrupt (nINT) output when nCS is high. |+| 7 | INH/LIMP | output | High-voltage inhibit output used to enable/disable the system voltage regulator and power rails. On TCAN1144-Q1 and TCAN1146-Q1 this pin can be configured as a limp-home output; on TCAN1145-Q1 it functions as INH only. |+| 8 | SCLK | input | SPI serial clock input from the MCU. Clocks SDI in and SDO out on the appropriate edges. |+| 9 | WAKE | input | High-voltage local wake-up input. Edge on this pin wakes the device from sleep. Absolute voltage range −18V to +42V. |+| 10 | VSUP | power_in | High-voltage battery supply input. Feeds the INH and wake circuitry directly from the vehicle battery rail. |+| 11 | SDI | input | SPI serial data input from the MCU. Sampled on SCLK edges while nCS is asserted low. |+| 12 | CANL | bidirectional | Low-side CAN bus I/O. Driven low in the dominant state and biased to VCC/2 in the recessive state. ±58V bus fault protection. |+| 13 | CANH | bidirectional | High-side CAN bus I/O. Driven high in the dominant state and biased to VCC/2 in the recessive state. ±58V bus fault protection. |+| 14 | nCS | input | Active-low SPI chip-select input from the MCU. Enables SPI transactions and selects the nINT/SDO pin function. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-14 |+| Category | Comm/UART |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `TCAN1145DRQ1D`+- `TCAN1145DRQ1`+- `TCAN1145DRQ1DMT`+- `TCAN1145DRQ1DYY`++## CAD (KiCad official)++- Symbol: `TCAN1145DRQ1`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/tcan1145drq1-datasheet.pdf) (116 pp, sha256 `276a9067cc1d77a4`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
