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 host controller. LOW drives a dominant bus state; HIGH allows the recessive state. Internal pull-up biases the bus to recessive if left floating. Logic input voltage range -0.3 V to VIO+0.3 V (max +7 V). |+| 2 | GND | power_in | Device ground reference. All voltage measurements are referenced to this terminal. |+| 3 | VCC | power_in | Transceiver 5 V supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. Decouple to GND with local bypass capacitors. |+| 4 | RXD | output | CAN receive data output to the host controller. LOW indicates a dominant bus state; HIGH indicates recessive. Output current rated ±8 mA max; drives to VCC rail on non-'V' variants. |+| 5 | NC | unconnected | No Connect on the HG (non-'V') variant. Pin 5 is repurposed as VIO only on devices with the 'V' suffix; on TCAN1051HG it has no internal connection and may be left floating or tied to GND. |+| 6 | CANL | bidirectional | Low-side CAN differential bus I/O. Together with CANH forms the twisted-pair CAN bus. HG variant supports ±70 V bus fault protection and ±16 kV HBM ESD to GND. |+| 7 | CANH | bidirectional | High-side CAN differential bus I/O. Together with CANL forms the twisted-pair CAN bus. HG variant supports ±70 V bus fault protection and ±16 kV HBM ESD to GND. |+| 8 | S | input | Silent (listen-only) mode control input, active HIGH. Drive LOW for normal mode; drive HIGH to place the transceiver in silent mode where the transmitter is disabled but the receiver remains active. Logic input voltage range -0.3 V to VIO+0.3 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `TCAN1051HGDRHGDR`+- `TCAN1051HGDRHGD`+- `TCAN1051HGDRHGDRB`+- `TCAN1051HGDRHGVDR`++## CAD (KiCad official)++- Symbol: `TCAN1051HGDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tcan1051hg.pdf) (37 pp, sha256 `9d4561ff8b0892f7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
