LM193DR

UMW · Comparators · SOP-8

LM193DR from UMW, 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 OUT_A output Open-collector output of comparator A. Requires an external pull-up resistor. Can sink up to 16 mA typical.
2 IN_A- input Inverting input of comparator A. Common-mode input voltage range includes ground.
3 IN_A+ input Non-inverting input of comparator A. Common-mode input voltage range includes ground.
4 GND power_in Ground / negative supply (V-). Typically tied to 0 V for single-supply operation.
5 IN_B+ input Non-inverting input of comparator B. Common-mode input voltage range includes ground.
6 IN_B- input Inverting input of comparator B. Common-mode input voltage range includes ground.
7 OUT_B output Open-collector output of comparator B. Requires an external pull-up resistor. Can sink up to 16 mA typical.
8 VCC power_in Positive supply voltage (V+). Operating range 2 V to 36 V single supply, or ±1 V to ±18 V dual supply.

CAD (KiCad official)

  • Symbol: LM193DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm193dr-etched.step / lm193dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm193dr.step / lm193dr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm193dr.step 122 KB You want the bare part, or you mark your own boards.
lm193dr-etched.step 1.6 MB You want the part with LM193DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 397 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.
