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 | Comparator 1 open-collector output. Requires an external pull-up resistor to VCC (typ. 1 kΩ-100 kΩ). Sinks up to ~16 mA when the output is low. |+| 2 | 1IN- | input | Comparator 1 inverting input. When V(1IN-) > V(1IN+), the open-collector output pulls low. |+| 3 | 1IN+ | input | Comparator 1 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V. |+| 4 | GND | power_in | Negative supply / ground reference. Tied to system ground in single-supply operation, or to V- in split-supply operation. |+| 5 | 2IN+ | input | Comparator 2 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V. |+| 6 | 2IN- | input | Comparator 2 inverting input. When V(2IN-) > V(2IN+), the open-collector output pulls low. |+| 7 | 2OUT | output | Comparator 2 open-collector output. Requires an external pull-up resistor to VCC. Sinks up to ~16 mA when low. |+| 8 | VCC | power_in | Positive supply pin. Single-supply range 2 V to 36 V, or split-supply ±1 V to ±18 V. Decouple with a 0.1 µF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOP-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `LM393DRG`++## CAD (KiCad official)++- Symbol: `LM393DRG`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8604446299760975872) (10 pp, sha256 `d19a446ca7fed173`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
