SN65HVD234DR 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 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).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd234dr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd234dr-etched.step`	2.5 MB	You want the part with `SN65HVD234DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 610 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.
