LM293DR2G

onsemi · Comparators · SOIC-8

LM293DR2G from onsemi, in a SOIC-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 OUTA output Open-collector output of comparator A. Sinks up to 16 mA typical (6 mA min) with VOL ≤ 400 mV at 4 mA; requires an external pull-up resistor to VCC (or another supply up to 36 V). Output leakage 0.1 nA typ.
2 IN-A input Inverting input of comparator A. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ (250 nA max), input offset current 5 nA typ. Must not go more than 0.3 V below the negative supply.
3 IN+A input Non-inverting input of comparator A. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ. Differential input voltage may equal the full supply voltage.
4 GND power_in Negative supply / ground. Tied to 0 V in single-supply operation, or to the negative rail (down to −18 V) in split-supply operation.
5 IN+B input Non-inverting input of comparator B. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ (250 nA max). Differential input voltage may equal the full supply voltage.
6 IN-B input Inverting input of comparator B. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ. Must not go more than 0.3 V below the negative supply.
7 OUTB output Open-collector output of comparator B. Sinks up to 16 mA typical (6 mA min) with VOL ≤ 400 mV at 4 mA; requires an external pull-up resistor. Output leakage 0.1 nA typ.
8 VCC power_in Positive supply. Single-supply range 2.0 V to 36 V, or ±1.0 V to ±18 V split supply. Typical supply current 0.4 mA (1.0 mA max) for both comparators, independent of supply voltage.

  • 3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm293dr2g.step 122 KB You want the bare part, or you mark your own boards.
lm293dr2g-etched.step 2.1 MB You want the part with LM293DR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 509 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.

Provenance

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

  • Datasheet: onsemi datasheet (13 pp, sha256 b87721993d627de6, 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).
