LM2901DR2G from onsemi, 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 | OUT2 | output | Open-collector output of comparator 2. Requires external pull-up resistor to the desired logic-high rail. Sinks up to ~16 mA typical. |
| 2 | OUT1 | output | Open-collector output of comparator 1. Requires external pull-up resistor. |
| 3 | VCC | power_in | Positive supply pin. Single-supply operation 3 V to 36 V, or split supply ±1.5 V to ±18 V. |
| 4 | IN1- | input | Inverting input of comparator 1. Common-mode range includes ground (V- to VCC-1.5 V). |
| 5 | IN1+ | input | Non-inverting input of comparator 1. Common-mode range includes ground. |
| 6 | IN2- | input | Inverting input of comparator 2. |
| 7 | IN2+ | input | Non-inverting input of comparator 2. |
| 8 | IN3- | input | Inverting input of comparator 3. |
| 9 | IN3+ | input | Non-inverting input of comparator 3. |
| 10 | OUT3 | output | Open-collector output of comparator 3. Requires external pull-up resistor. |
| 11 | OUT4 | output | Open-collector output of comparator 4. Requires external pull-up resistor. |
| 12 | IN4+ | input | Non-inverting input of comparator 4. |
| 13 | IN4- | input | Inverting input of comparator 4. |
| 14 | GND | power_in | Negative supply / ground pin. Tied to V- in split-supply operation, or ground in single-supply operation. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 606 faces against 237 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.
