LM2901AVQDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output pin of the comparator 2 as labeled in the datasheet's pin table; the datasheet notes some manufacturers transpose the channel 1 and 2 names, which is electrically identical. |
| 2 | OUT2 | output | Output pin of the comparator 1 as labeled in the datasheet's pin table; the datasheet notes some manufacturers transpose the channel 1 and 2 names, which is electrically identical. |
| 3 | VCC | power_in | Positive supply pin for the device. |
| 4 | IN2- | input | Negative input pin of the comparator 1. |
| 5 | IN2+ | input | Positive input pin of the comparator 1. |
| 6 | IN1- | input | Negative input pin of the comparator 2. |
| 7 | IN1+ | input | Positive input pin of the comparator 2. |
| 8 | IN3- | input | Negative input pin of the comparator 3. |
| 9 | IN3+ | input | Positive input pin of the comparator 3. |
| 10 | IN4- | input | Negative input pin of the comparator 4. |
| 11 | IN4+ | input | Positive input pin of the comparator 4. |
| 12 | GND | power_in | Negative supply pin for the device. |
| 13 | OUT4 | output | Output pin of the comparator 4. |
| 14 | OUT3 | output | Output pin of the comparator 3. |
