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 | OUT | output | Comparator output. CMOS/TTL-compatible push-pull output; rail-to-rail swing (VOH = VDD - 0.166V, VOL = 132mV typical at IO = 4mA). Short-circuit source/sink currents ~42.6/43.7mA typical. |+| 2 | VSS | power_in | Negative supply / ground. Referenced to GND in single-supply operation (2.7V to 5.5V); may be tied to a negative rail for dual ±1.35V to ±2.75V supply operation. |+| 3 | IN+ | input | Non-inverting comparator input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 6pA typical, input offset voltage 5mV max. |+| 4 | IN- | input | Inverting comparator input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 6pA typical, 3mV internal hysteresis referenced between inputs. |+| 5 | VDD | power_in | Positive supply. Single-supply +2.7V to +5.5V (absolute max +7.5V). Bypass with 0.1uF ceramic capacitor placed close to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SC-70-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `GS8743-CR`+- `GS8743-CRTR`++## CAD (KiCad official)++- Symbol: `GS8743-CR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Gainsil datasheet](docs/gs8743-cr-datasheet.pdf) (10 pp, sha256 `01cf762eed96a4a8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
