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 | D | input | CAN transmit data input (TXD / driver input). LOW drives the bus dominant; HIGH leaves the bus recessive. Internally pulled up to VCC. |+| 2 | GND | power_in | Ground reference for the device. All voltages are referenced to this pin. |+| 3 | VCC | power_in | Transceiver supply voltage, 3.3V nominal (3.0V to 3.6V range). Absolute max -0.3V to +6V. |+| 4 | R | output | CAN receive data output (RXD / driver output). LOW for dominant bus state, HIGH for recessive. Output current limits ±11 mA. |+| 5 | SHDN | input | Shutdown input, CMOS/TTL compatible. Drive HIGH to enter low-current off mode; internal pull-down to GND keeps the device active if left open. VIH ≥ 2V, VIL ≤ 0.8V. |+| 6 | CANL | bidirectional | Low-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V. |+| 7 | CANH | bidirectional | High-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V. |+| 8 | RS | input | Mode select pin. Strong pull-down to GND (<0.33 VCC) selects high-speed mode; strong pull-up to VCC (>0.75 VCC) selects low-power/standby mode; a 10 kΩ to 100 kΩ pull-down to GND selects slope-control mode with adjustable driver transition times. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SIT |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `SIT3051ESA`+- `SIT3051ESATK`++## CAD (KiCad official)++- Symbol: `SIT3051ESA`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SIT datasheet](docs/sit3051esa-datasheet.pdf) (18 pp, sha256 `6d6af5f032b778e0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
