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.
