SIT3088EEUA

SIT · RS-485 / RS-422 ICs · MSOP-8

SIT3088EEUA from SIT, in a MSOP-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. When /RE is low and (A - B) >= -10 mV, RO is high; when (A - B) <= -200 mV, RO is low. High-impedance when /RE is high.
2 /RE input Receiver Output Enable (active low). Drive /RE low to enable RO; RO is high-impedance when /RE is high. Drive /RE high and DE low to enter low-power shutdown mode.
3 DE input Driver Output Enable (active high). Drive DE high to enable driver outputs A and B; outputs are high-impedance when DE is low. Drive /RE high and DE low to enter low-power shutdown mode.
4 DI input Driver Input. With DE high, a low on DI forces A low and B high; a high on DI forces A high and B low.
5 GND power_in Ground reference for the device. All voltages are referenced to this pin.
6 A bidirectional Non-inverting receiver input and non-inverting driver output (RS-485/RS-422 bus line A). Withstands -15V to +15V bus fault, 15kV HBM ESD protected.
7 B bidirectional Inverting receiver input and inverting driver output (RS-485/RS-422 bus line B). Withstands -15V to +15V bus fault, 15kV HBM ESD protected.
8 VCC power_in Positive supply, 3.0 V to 5.5 V operating range (6.5 V absolute max). Bypass locally to GND with a 0.1 µF ceramic capacitor.

CAD (KiCad official)

  • Symbol: SIT3088EEUA
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: sit3088eeua-etched.step / sit3088eeua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sit3088eeua.step / sit3088eeua.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sit3088eeua.step 123 KB You want the bare part, or you mark your own boards.
sit3088eeua-etched.step 2.6 MB You want the part with SIT3088EEUA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 617 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: SIT datasheet (19 pp, sha256 7b3ff7bae541908c, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
