TS391IYLT

STMicroelectronics · Comparators · SOT-23-5

TS391IYLT from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Open-collector comparator output, TTL/DTL/ECL/CMOS compatible, can be pulled up to 36 V even if VCC is lower, with sink current of 6 mA min at Vo = 1.5 V and short-circuit current of about 20 mA.
2 VCC- power_in Negative supply pin, connected to ground in single-supply operation (0 V) or to the negative rail in dual-supply operation down to -18 V.
3 IN- input Inverting comparator input, with common-mode range of 0 V to (VCC+) - 1.5 V at 25 °C and not more than 0.3 V below the negative supply.
4 IN+ input Non-inverting comparator input, with common-mode range of 0 V to (VCC+) - 1.5 V at 25 °C and not more than 0.3 V below the negative supply.
5 VCC+ power_in Positive supply pin, operating range of 2 V to 36 V single supply (or ±1 V to ±18 V dual supplies), with absolute maximum of 36 V.

CAD (KiCad official)

  • Symbol: TS391IYLT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ts391iylt-etched.step / ts391iylt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts391iylt.step / ts391iylt.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (14 pp, sha256 5535252141921784, retrieved 2026-11-05, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
