TCAN332DR 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	TXD	input	CAN transmit data input. LOW drives dominant, HIGH drives recessive bus state. Integrated pull-up. VIH ≥ 2V, VIL ≤ 0.8V.
2	GND	power_in	Ground connection.
3	VCC	power_in	3.3-V supply voltage. Recommended operating range 3.0 V to 3.6 V.
4	RXD	output	CAN receive data output. LOW for dominant and HIGH for recessive bus states. Tri-state output. VOH ≥ 0.8 × VCC at IO = -2 mA.
5	NC	unconnected	No Connect - Not internally connected. TCAN332 is normal-mode-only, so this pin has no function.
6	CANL	bidirectional	Low-level CAN bus line. ±12V common-mode range, ±14V fault protection, ±12kV IEC 61000-4-2 ESD contact discharge protection.
7	CANH	bidirectional	High-level CAN bus line. ±12V common-mode range, ±14V fault protection, ±12kV IEC 61000-4-2 ESD contact discharge protection.
8	NC	unconnected	No Connect - Not internally connected. TCAN332 is normal-mode-only, so this pin has no function.

CAD (KiCad official)

3D model: SOIC-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tcan332dr.step`	122 KB	You want the bare part, or you mark your own boards.
`tcan332dr-etched.step`	2.0 MB	You want the part with `TCAN332DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 487 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.
