LM293ADR

Texas Instruments · Comparators · SOIC-8

LM293ADR from Texas Instruments, 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 1OUT output Open-collector output of comparator 1. Requires an external pull-up resistor to VCC. Can sink up to 16 mA typical.
2 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to VCC. Can sink up to 16 mA typical.
3 VCC power_in Positive supply voltage. Single supply operation 2 V to 36 V, or dual supply ±1 V to ±18 V.
4 2IN- input Inverting input of comparator 2. Common-mode input voltage range extends to ground (VCC-).
5 2IN+ input Non-inverting input of comparator 2. Common-mode input voltage range extends to ground (VCC-).
6 1IN- input Inverting input of comparator 1. Common-mode input voltage range extends to ground (VCC-).
7 1IN+ input Non-inverting input of comparator 1. Common-mode input voltage range extends to ground (VCC-).
8 GND power_in Ground / negative supply pin (VCC-). Connect to 0 V for single-supply operation or to the negative rail for dual-supply operation.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm293adr.step 122 KB You want the bare part, or you mark your own boards.
lm293adr-etched.step 1.8 MB You want the part with LM293ADR 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 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: Texas Instruments datasheet (56 pp, sha256 24c6b3c03dd65dfd, 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).
