SN65HVD232DR 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 (also called TXD/driver input). LOW drives a dominant bus state; HIGH allows the bus to go recessive. Digital input rated -0.5 V to VCC+0.5 V.
2	GND	power_in	Ground / device return connection. All voltages referenced to this network ground terminal.
3	VCC	power_in	Transceiver 3.3 V supply voltage input. Absolute max 6 V; recommended operating from a single 3.3 V rail.
4	R	output	CAN receive data output (also called RXD/receiver output). LOW when the bus is dominant, HIGH when recessive. Output current rated ±11 mA.
5	NC	unconnected	No Connect on SN65HVD232. This pin is the Vref (VCC/2) output on the sibling SN65HVD230/231 devices but is unused on the SN65HVD232.
6	CANL	bidirectional	Low-level CAN bus line. Differential bus terminal; withstands -4 V to 16 V continuous and ±25 V transients (through 100 Ω). Common-mode operating range -2 V to 7 V.
7	CANH	bidirectional	High-level CAN bus line. Differential bus terminal; withstands -4 V to 16 V continuous and ±25 V transients (through 100 Ω). Common-mode operating range -2 V to 7 V.
8	NC	unconnected	No Connect on SN65HVD232. This pin is the RS mode-select input on the sibling SN65HVD230/231 devices; the SN65HVD232 has no standby/sleep or slope-control mode, so the pin is unused.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd232dr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd232dr-etched.step`	2.6 MB	You want the part with `SN65HVD232DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 623 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.
