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 range GND+0.2 V to VCC-0.2 V. Input offset +/-5 mV max, internal hysteresis ~5 mV typ, input resistance >100 GOhm. |+| 2 | GND | power_in | Ground / negative supply reference for the comparator. |+| 3 | -IN | input | Inverting comparator input. Common-mode range GND+0.2 V to VCC-0.2 V. Datasheet pin-description table mislabels this as '+VIN inverting input'; the pin-configuration diagram (SOT23-5 top view) clearly shows pin 3 as -IN. |+| 4 | OUTPUT | output | Comparator digital output, rail-to-rail CMOS/TTL-compatible Class-AB push-pull. VOH >= VCC-0.3 V, VOL <= GND+0.3 V. Short-circuit current to VDD ~25 mA. Rise ~35 ns, fall ~28 ns, propagation delay ~140 ns at 100 mV overdrive. |+| 5 | VCC | power_in | Positive supply. Operating range 2.7-5.5 V (absolute max 5.5 V). Quiescent current ~200 uA. PSRR ~63 dB. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HTCSEMI |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `HT331VRTZ`+- `HT331VRTZRMZ`+- `HT331VRTZRZ`++## CAD (KiCad official)++- Symbol: `HT331VRTZ`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HTCSEMI datasheet](docs/ht331vrtz-datasheet.pdf) (7 pp, sha256 `a9fab51f2b1754c2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
