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 analog input of the op-amp. Common-mode input range includes ground and extends to VDD-1.5V. Typical input bias current 20nA. |+| 2 | VSS | power_in | Negative supply / ground. Connect to GND in single-supply operation (3V to 36V VDD) or to the negative rail (down to -18V) in dual-supply operation. Bypass with a 0.1µF ceramic capacitor to ground in split-supply designs. |+| 3 | IN- | input | Inverting analog input of the op-amp. Same common-mode range and bias current characteristics as IN+. |+| 4 | OUT | output | Op-amp output. Swings from 0V to VCC-1.5V; sources/sinks 40mA typical (60mA max) into a 10Ω load to VS/2. Output high VOH ≥12V and low VOL ≤5mV typical at RL=10kΩ with VS=15V. |+| 5 | VDD | power_in | Positive supply. Single-supply range 3V to 36V, or up to +18V in dual-supply operation. Bypass with a 0.1µF ceramic capacitor to VSS placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321H-TR`+- `LM321H-TRLM358H-SR`+- `LM321H-TRLM358H-MR`+- `LM321H-TRLM324H-SR`+- `LM321H-TRLM324H-TR`++## CAD (KiCad official)++- Symbol: `LM321H-TR`+- 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:** [Unknown datasheet](docs/lm321h-tr-datasheet.pdf) (14 pp, sha256 `1b038a6ed7d0cd56`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
