SN65HVD235DR from Texas Instruments, in a SOIC-8. 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 allows the recessive state. LVTTL/5-V tolerant input referenced to VCC.
2	GND	power_in	Ground reference for the transceiver and CAN bus signalling.
3	VCC	power_in	Transceiver 3.3-V supply voltage (nominal 3.3 V, absolute max 7 V). Decouple with local 100 nF ceramic 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.
5	AB	input	Autobaud loopback mode input pin (SN65HVD235 variant). A logic high places the bus driver output in high-impedance while the receiver remains active and an internal D-to-R loopback is enabled to assist baud-rate detection or autobaud.
6	CANL	bidirectional	Low-level CAN differential bus line. Fault-protected to ±36 V and transient-protected to ±100 V through 100 Ω (per ISO 7637).
7	CANH	bidirectional	High-level CAN differential bus line. Fault-protected to ±36 V and transient-protected to ±100 V through 100 Ω.
8	RS	input	Mode select 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 pulldown resistor selects slope-control mode (≈15 V/µs at 10 kΩ, ≈2 V/µs at 100 kΩ).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd235dr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd235dr-etched.step`	2.6 MB	You want the part with `SN65HVD235DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 625 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
