Requires an external pull-up resistor to a positive rail (typ. ≤ Vcc+). Low output saturation voltage 250 mV typ at Isink = 4 mA; sink up to ~20 mA short-circuit to Vcc+. |+| 2 | Output1 | output | Open-collector output of comparator 1. Requires an external pull-up resistor. Same drive characteristics as Output2. |+| 3 | VCC+ | power_in | Positive supply rail. Single-supply operation 2 to 36 V, or +Vcc in a split ±1 to ±18 V supply. Typ quiescent current 1.1 mA independent of Vcc. |+| 4 | Inverting input 1 | input | Inverting (-) input of comparator 1. Common-mode range includes ground: 0 to (Vcc+ − 1.5) V. Input bias current 25 nA typ; input offset ±1 mV typ (±2 mV max for A grade). |+| 5 | Non-inverting input 1 | input | Non-inverting (+) input of comparator 1. Common-mode range 0 to (Vcc+ − 1.5) V; differential input voltage rating ±36 V. |+| 6 | Inverting input 2 | input | Inverting (-) input of comparator 2. Same electrical characteristics as input 1. |+| 7 | Non-inverting input 2 | input | Non-inverting (+) input of comparator 2. |+| 8 | Inverting input 3 | input | Inverting (-) input of comparator 3. |+| 9 | Non-inverting input 3 | input | Non-inverting (+) input of comparator 3. |+| 10 | Inverting input 4 | input | Inverting (-) input of comparator 4. |+| 11 | Non-inverting input 4 | input | Non-inverting (+) input of comparator 4. |+| 12 | VCC- | power_in | Negative supply / ground rail. Tie to GND in single-supply operation, or to −Vcc in a split ±1 to ±18 V supply. |+| 13 | Output4 | output | Open-collector output of comparator 4. Requires external pull-up. |+| 14 | Output3 | output | Open-collector output of comparator 3. Requires external pull-up. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `LM239ADTDT`+- `LM239ADTD`+- `LM239ADTPT`+- `LM239ADTQT`++## CAD (KiCad official)++- Symbol: `LM239ADT`+- 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:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lm239adt.pdf) (19 pp, sha256 `5adc47258717f516`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
