GS8743-TR

Gainsil · Comparators · SOT-23-5

GS8743-TR from Gainsil, 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. CMOS/TTL-compatible, rail-to-rail. Typical output swing within 166mV of VDD (VOH) and 132mV of VSS (VOL) at 4mA load; short-circuit source/sink current ~42/43mA at VS=5V.
2 VSS power_in Negative supply / ground pin. Connect to 0V in single-supply operation (2.7V to 5.5V across VDD-VSS), or to the negative rail in dual-supply operation (±1.35V to ±2.75V).
3 IN+ input Non-inverting analog input. Rail-to-rail common-mode range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). Max input voltage limited to VSS-0.5V to VDD+0.5V (absolute).
4 IN- input Inverting analog input. Rail-to-rail common-mode range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). Input bias current typ 6pA; input offset current typ 4pA.
5 VDD power_in Positive supply pin. Operating range 2.7V to 5.5V single-supply (absolute max 7.5V vs VSS). Quiescent current 1.3mA typ. Bypass with 0.1µF ceramic capacitor placed close to the pin.

CAD (KiCad official)

  • Symbol: GS8743-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs8743-tr-etched.step / gs8743-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8743-tr.step / gs8743-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs8743-tr.step 85 KB You want the bare part, or you mark your own boards.
gs8743-tr-etched.step 1.8 MB You want the part with GS8743-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 443 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:
