TS391ILT

STMicroelectronics · Comparators · SOT-23-5

TS391ILT from STMicroelectronics, in a SOT-23-5. 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 output Comparator push-pull output. Drives high when V(IN+) > V(IN-), low otherwise. Rail-to-rail push-pull CMOS output.
2 V- power_in Negative supply / ground. Connect to GND for single-supply operation, or to negative rail for dual-supply operation. V+ − V- range: 2.7 V to 16 V.
3 IN+ input Non-inverting comparator input. Rail-to-rail input common-mode range (V- to V+).
4 IN- input Inverting comparator input. Rail-to-rail input common-mode range (V- to V+).
5 V+ power_in Positive supply. Single-supply range 2.7 V to 16 V, or ±1.35 V to ±8 V dual supply. Typical quiescent current 9 µA.

Ordering variants

Same part, different packaging or reel option.

  • TS391ILT

CAD (KiCad official)

  • Symbol: TS391ILT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ts391ilt-etched.step / ts391ilt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts391ilt.step / ts391ilt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ts391ilt.step 85 KB You want the bare part, or you mark your own boards.
ts391ilt-etched.step 1.5 MB You want the part with TS391ILT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 365 faces against 102 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: STMicroelectronics datasheet (14 pp, sha256 5535252141921784, retrieved 2026-08-17, tier: manufacturer)
  • 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).
