ISO1042DWVR from Texas Instruments, in a SOIC-8-300mil. 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	VCC1	power_in	Digital-side (side 1) supply voltage. Operating range 1.71 V to 5.5 V (1.8 V, 2.5 V, 3.3 V, or 5 V logic). Bypass locally to GND1.
2	TXD	input	CAN transmit data input from the host controller. LOW drives a dominant bus state, HIGH allows a recessive bus state. Referenced to VCC1/GND1 logic levels.
3	RXD	output	CAN receive data output to the host controller. LOW indicates dominant bus state, HIGH indicates recessive bus state. Output current limited to ±15 mA (absolute max).
4	GND1	power_in	Digital-side (side 1) ground reference for VCC1, TXD, and RXD.
5	GND2	power_in	Transceiver-side (side 2) ground reference for VCC2, CANH, and CANL. Isolated from GND1 by the 5000 Vrms SiO2 barrier.
6	CANL	bidirectional	Low-level CAN bus line. Withstands ±70 V DC bus fault and ±16 kV HBM ESD to GND2. Tolerates -70 V to 70 V bus voltage and -70 V to 70 V differential (absolute max).
7	CANH	bidirectional	High-level CAN bus line. Withstands ±70 V DC bus fault and ±16 kV HBM ESD to GND2. Tolerates -70 V to 70 V bus voltage and -70 V to 70 V differential (absolute max).
8	VCC2	power_in	Transceiver-side (side 2) supply voltage. Operating range 4.5 V to 5.5 V. Bypass locally to GND2.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`iso1042dwvr.step`	122 KB	You want the bare part, or you mark your own boards.
`iso1042dwvr-etched.step`	2.1 MB	You want the part with `ISO1042DWVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 538 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.
