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 | 1OUT | output | Open-collector output of comparator 1. Requires an external pull-up resistor to VCC (typical 5.1 kΩ). Sinks up to 6 mA (min) / 21 mA (typ) with VOL ≤ 1.5 V; low-level output voltage ≤ 400 mV at ISINK = 4 mA. |+| 2 | 1IN- | input | Inverting (negative) input of comparator 1. Common-mode input range extends from V- (ground) to (V+) - 1.5 V. Differential input voltage up to ±36 V; input bias current typically -25 nA. |+| 3 | 1IN+ | input | Non-inverting (positive) input of comparator 1. Common-mode input range includes ground. Input bias current typically -25 nA; must not go more than 0.3 V below V-. |+| 4 | GND | power_in | Ground / negative supply (V-). For single-supply operation, connect to system ground. |+| 5 | 2IN+ | input | Non-inverting (positive) input of comparator 2. Common-mode input range includes ground; input bias current typically -25 nA. |+| 6 | 2IN- | input | Inverting (negative) input of comparator 2. Common-mode input range V- to (V+) - 1.5 V; differential input voltage up to ±36 V. |+| 7 | 2OUT | output | Open-collector output of comparator 2. Requires an external pull-up resistor to VCC. Sinks up to 6 mA (min) with VOL ≤ 1.5 V; compatible with TTL, MOS, and CMOS logic. |+| 8 | VCC | power_in | Positive supply (V+). Operating range 2 V to 30 V (LM293); absolute maximum 36 V. Quiescent current typically 0.45 mA at VCC = 5 V. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM293DRDR`+- `LM293DRD`+- `LM293DRDGK`+- `LM293DRP`+- `LM293DRPW`++## CAD (KiCad official)++- Symbol: `LM293DR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lm293.pdf) (56 pp, sha256 `24c6b3c03dd65dfd`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
