LM139DR

Texas Instruments · Comparators · SOIC-14

LM139DR from Texas Instruments, in a SOIC-14. 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 1OUT output Open-collector output of comparator 1. Requires an external pull-up resistor to VCC (or another rail up to 36 V). Sinks up to 20 mA (16 mA guaranteed).
2 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor. Sinks up to 20 mA.
3 VCC power_in Positive supply. Single-supply operation from 2 V to 30 V (LM139/LM339/LM239/LM2901) or split supplies up to ±15 V. Absolute maximum 36 V.
4 2IN- input Inverting (negative) input of comparator 2. Common-mode range includes ground; input voltage range -0.3 V to 36 V.
5 2IN+ input Non-inverting (positive) input of comparator 2. Common-mode range includes ground; input voltage range -0.3 V to 36 V.
6 1IN- input Inverting (negative) input of comparator 1. Common-mode range includes ground; input voltage range -0.3 V to 36 V.
7 1IN+ input Non-inverting (positive) input of comparator 1. Common-mode range includes ground; input voltage range -0.3 V to 36 V.
8 3IN- input Inverting (negative) input of comparator 3. Common-mode range includes ground.
9 3IN+ input Non-inverting (positive) input of comparator 3. Common-mode range includes ground.
10 4IN- input Inverting (negative) input of comparator 4. Common-mode range includes ground.
11 4IN+ input Non-inverting (positive) input of comparator 4. Common-mode range includes ground.
12 GND power_in Ground / negative supply. In single-supply operation this pin is tied to system ground.
13 4OUT output Open-collector output of comparator 4. Requires an external pull-up resistor.
14 3OUT output Open-collector output of comparator 3. Requires an external pull-up resistor.

  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: lm139dr-etched.step / lm139dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm139dr.step / lm139dr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (53 pp, sha256 b8b91e2b545800b8, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
