Requires an external pull-up resistor to a positive supply. Sinks current when the inverting input is above the non-inverting input. |+| 2 | 2OUT | output | Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply. |+| 3 | V+ | 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 range includes ground (V-). |+| 5 | 2IN+ | input | Non-inverting input of comparator 2. Common-mode input range includes ground (V-). |+| 6 | 1IN- | input | Inverting input of comparator 1. Common-mode input range includes ground (V-). |+| 7 | 1IN+ | input | Non-inverting input of comparator 1. Common-mode input range includes ground (V-). |+| 8 | 3IN+ | input | Non-inverting input of comparator 3. Common-mode input range includes ground (V-). |+| 9 | 3IN- | input | Inverting input of comparator 3. Common-mode input range includes ground (V-). |+| 10 | 4IN+ | input | Non-inverting input of comparator 4. Common-mode input range includes ground (V-). |+| 11 | 4IN- | input | Inverting input of comparator 4. Common-mode input range includes ground (V-). |+| 12 | GND | power_in | Ground / negative supply (V-). Tie to system ground in single-supply operation, or to the negative rail in dual-supply operation. |+| 13 | 4OUT | output | Open-collector output of comparator 4. Requires an external pull-up resistor to a positive supply. |+| 14 | 3OUT | output | Open-collector output of comparator 3. Requires an external pull-up resistor to a positive supply. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `LP339DR`+- `LP339DRD`+- `LP339DRPWR`+- `LP339DRPW`++## CAD (KiCad official)++- Symbol: `LP339DR`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lp339.pdf) (15 pp, sha256 `568cdf139073fc1a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
