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 a dominant bus state; HIGH drives a recessive bus state. LVTTL/5-V tolerant input. |+| 2 | GND | power_in | Device ground reference. All voltage measurements are with respect to this pin. |+| 3 | VCC | power_in | Transceiver 3.3-V supply voltage. Recommended operating range 3 V to 3.6 V. Decouple locally to GND. |+| 4 | R | output | CAN receive data output (RXD, receiver output). LOW indicates a dominant bus state; HIGH indicates a recessive bus state. LVTTL output, IOH/IOL up to ±10 mA. |+| 5 | LBK | input | Loopback mode input (SN65HVD233 only). A logic HIGH on LBK places CANH/CANL in a high-impedance state while keeping the internal D→R path active, enabling self-diagnostic loopback without disturbing the bus. |+| 6 | CANL | bidirectional | Low-level CAN differential bus line. Withstands bus faults up to ±36 V and transient pulses up to ±100 V (through 100 Ω). Common-mode range -7 V to 12 V. |+| 7 | CANH | bidirectional | High-level CAN differential bus line. Withstands bus faults up to ±36 V and transient pulses up to ±100 V (through 100 Ω). Common-mode range -7 V to 12 V. |+| 8 | Rs | input | Mode select / slope control pin. Strong pulldown to GND selects high-speed mode; strong pullup to VCC selects low-power standby (listen-only) mode; a 10-kΩ to 100-kΩ resistor to GND sets adjustable slope control (≈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++- `SN65HVD233DRD`+- `SN65HVD233DRDR`++## CAD (KiCad official)++- Symbol: `SN65HVD233DR`+- 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/sn65hvd233.pdf) (38 pp, sha256 `79975b227bd3ba6f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
