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 | OUTA | output | Open-collector output of comparator A. Sinks up to 16 mA typical (6 mA min) with VOL ≤ 400 mV at 4 mA; requires an external pull-up resistor to VCC (or another supply up to 36 V). Output leakage 0.1 nA typ. |+| 2 | IN-A | input | Inverting input of comparator A. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ (250 nA max), input offset current 5 nA typ. Must not go more than 0.3 V below the negative supply. |+| 3 | IN+A | input | Non-inverting input of comparator A. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ. Differential input voltage may equal the full supply voltage. |+| 4 | GND | power_in | Negative supply / ground. Tied to 0 V in single-supply operation, or to the negative rail (down to −18 V) in split-supply operation. |+| 5 | IN+B | input | Non-inverting input of comparator B. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ (250 nA max). Differential input voltage may equal the full supply voltage. |+| 6 | IN-B | input | Inverting input of comparator B. Common-mode range 0 V to (VCC − 1.5 V); input bias current 20 nA typ. Must not go more than 0.3 V below the negative supply. |+| 7 | OUTB | output | Open-collector output of comparator B. Sinks up to 16 mA typical (6 mA min) with VOL ≤ 400 mV at 4 mA; requires an external pull-up resistor. Output leakage 0.1 nA typ. |+| 8 | VCC | power_in | Positive supply. Single-supply range 2.0 V to 36 V, or ±1.0 V to ±18 V split supply. Typical supply current 0.4 mA (1.0 mA max) for both comparators, independent of supply voltage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM293DR2GDR2G`+- `LM293DR2GDG`+- `LM293DR2GN`+- `LM293DR2GDM`+- `LM293DR2GDMR2`++## CAD (KiCad official)++- Symbol: `LM293DR2G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/lm293-d.pdf) (13 pp, sha256 `b87721993d627de6`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
