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 to a dominant state; HIGH lets the bus recess. |+| 2 | GND | power_in | Ground / reference return for the transceiver. |+| 3 | VCC | power_in | Transceiver 3.3-V supply voltage (nominal 3.3 V, absolute max 7 V). |+| 4 | R | output | CAN receive data output (RXD, receiver output). LOW for dominant bus state, HIGH for recessive bus state. |+| 5 | EN | input | Enable input pin (SN65HVD234). Logic HIGH enables normal mode (high speed or slope control); logic LOW places the device into ultra low-current sleep mode (typ. 50 nA). |+| 6 | CANL | bidirectional | Low-level CAN differential bus line. Withstands ±36 V bus fault and ±100 V transient (via 100 Ω), with ±16 kV HBM ESD protection. |+| 7 | CANH | bidirectional | High-level CAN differential bus line. Withstands ±36 V bus fault and ±100 V transient (via 100 Ω), with ±16 kV HBM ESD protection. |+| 8 | RS | input | Mode select pin. Strong pulldown to GND selects high-speed mode; strong pullup to VCC selects low-power standby mode; a 10 kΩ to 100 kΩ pulldown to GND selects slope control mode (≈15 V/µs at 10 kΩ, ≈2 V/µs at 100 kΩ). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SN65HVD234DRD`+- `SN65HVD234DRDR`++## CAD (KiCad official)++- Symbol: `SN65HVD234DR`+- 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/sn65hvd234.pdf) (38 pp, sha256 `79975b227bd3ba6f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
