MAX13085

Shanghai Siproin Microelectronics · RS-485/RS-422 ICs · SOP-8

MAX13085 from Shanghai Siproin Microelectronics, in a SOP-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 RO output Receiver output. If A-B ≥ -0.05V, RO is high; if A-B ≤ -0.2V, RO is low; if A and B are open or shorted, RO is high (fail-safe). High-impedance when /RE is high.
2 /RE input Receiver output enable (active low). RO is enabled when /RE is low and high-impedance when /RE is high. Driving /RE high while DE is low places the device into low-current shutdown.
3 DE input Driver output enable (active high). Driver outputs A and B are enabled when DE is high and are high-impedance when DE is low.
4 DI input Driver input. A low on DI forces output A low and output B high; a high on DI forces output A high and output B low. VIH ≥ 2.0V, VIL ≤ 0.8V.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting receiver input and non-inverting driver output (RS-485/RS-422 bus line A). Protected to ±15kV HBM ESD; common-mode range -7V to +12V.
7 B bidirectional Inverting receiver input and inverting driver output (RS-485/RS-422 bus line B). Protected to ±15kV HBM ESD; common-mode range -7V to +12V.
8 VDD power_in Positive supply voltage. Nominal +5V (±5%); +3.3V operation supported with maximum recommended data rate of 500kbps. Absolute maximum -0.3V to +7V.

Same part, different packaging or reel option.

  • MAX13085

CAD (KiCad official)

  • Symbol: MAX13085
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: max13085-etched.step / max13085-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max13085.step / max13085.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
max13085.step 122 KB You want the bare part, or you mark your own boards.
max13085-etched.step 1.9 MB You want the part with MAX13085 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 470 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.
