LM293DR

Texas Instruments · Comparators · SOIC-8

LM293DR 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 (typical 5.1 kΩ). Sinks up to 6 mA (min) / 21 mA (typ) with VOL ≤ 1.5 V; low-level output voltage ≤ 400 mV at ISINK = 4 mA.
2 1IN- input Inverting (negative) input of comparator 1. Common-mode input range extends from V- (ground) to (V+) - 1.5 V. Differential input voltage up to ±36 V; input bias current typically -25 nA.
3 1IN+ input Non-inverting (positive) input of comparator 1. Common-mode input range includes ground. Input bias current typically -25 nA; must not go more than 0.3 V below V-.
4 GND power_in Ground / negative supply (V-). For single-supply operation, connect to system ground.
5 2IN+ input Non-inverting (positive) input of comparator 2. Common-mode input range includes ground; input bias current typically -25 nA.
6 2IN- input Inverting (negative) input of comparator 2. Common-mode input range V- to (V+) - 1.5 V; differential input voltage up to ±36 V.
7 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to VCC. Sinks up to 6 mA (min) with VOL ≤ 1.5 V; compatible with TTL, MOS, and CMOS logic.
8 VCC power_in Positive supply (V+). Operating range 2 V to 30 V (LM293); absolute maximum 36 V. Quiescent current typically 0.45 mA at VCC = 5 V. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

  • Symbol: LM293DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm293dr-etched.step / lm293dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm293dr.step / lm293dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm293dr.step 122 KB You want the bare part, or you mark your own boards.
lm293dr-etched.step 1.7 MB You want the part with LM293DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 417 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:
