ISO1042DWVR

Texas Instruments · CAN Controllers · SOIC-8-300mil

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.

Ordering variants

Same part, different packaging or reel option.

  • ISO1042DWVR
  • ISO1042DWVRDWR

CAD (KiCad official)

  • Symbol: ISO1042DWVR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8-300mil (KiCad packages3D, STEP)
  • 3D model files: iso1042dwvr-etched.step / iso1042dwvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); iso1042dwvr.step / iso1042dwvr.glb are the bare package body.

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (44 pp, sha256 546f9d202ae2a275, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
