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 | IN+ | input | Non-inverting comparator input. Common-mode input voltage range extends from -0.1 V to (VCC+ - 1.5 V); input bias current 15 nA typ (250 nA max) at VCC+ = 2.7 V. |+| 2 | GND | power_in | Ground / negative supply reference (0 V). Single-supply operation with VCC+ referenced to this pin. |+| 3 | IN- | input | Inverting comparator input. Differential input voltage rating ±5.5 V; common-mode input voltage range includes ground. |+| 4 | OUT | output | Open-collector comparator output. Requires an external pull-up resistor to VCC+ (typ RL = 5.1 kΩ). Sinks up to 23 mA typ at VCC+ = 2.7 V; saturation voltage 200 mV typ at IO ≤ 1.5 mA. |+| 5 | VCC+ | power_in | Positive supply. Single-supply operating range 2.7 V to 5.5 V; absolute maximum 5.5 V. Typical supply current 40 µA at VCC+ = 2.7 V, 60 µA at VCC+ = 5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LMV331IDCKRIDCKR`+- `LMV331IDCKRIDCKT`+- `LMV331IDCKRIDBVR`+- `LMV331IDCKRIDBVT`++## CAD (KiCad official)++- Symbol: `LMV331IDCKR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmv331i.pdf) (30 pp, sha256 `f16c28a91f97444c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
