SN65HVD233DR 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 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).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd233dr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd233dr-etched.step`	2.7 MB	You want the part with `SN65HVD233DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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.
