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 | VS | power_in | Input-side ground (input ground reference for the LED driver / FAULT logic). |+| 2 | VCC1 | power_in | Positive input supply voltage, 3.3 V to 5.5 V. |+| 3 | FAULT | output | Fault output. Changes from high impedance to logic low within 5 us if the DESAT pin voltage exceeds an internal reference of 7 V. Open-collector output allowing multiple LTV-333J FAULT outputs to be wire-OR'd into a single fault bus to a microcontroller. |+| 4 | VS | power_in | Input-side ground (second VS pin, tied to input ground reference). |+| 5 | CATHODE | input | Cathode of the input LED (LED1 drive input). Drive with the input signal referenced to the ANODE pins to command the gate driver output. |+| 6 | ANODE | input | Anode of the input LED (LED1 drive input). |+| 7 | ANODE | input | Anode of the input LED (second ANODE pin, parallel with pin 6). |+| 8 | CATHODE | input | Cathode of the input LED (second CATHODE pin, parallel with pin 5). |+| 9 | VEE | power_in | Output-side negative supply (typically IGBT emitter-referenced negative rail). Same net as pin 12. |+| 10 | VCLAMP | output | Active Miller clamp output. Sinks Miller current from the IGBT gate to VEE during the off state to suppress parasitic turn-on. |+| 11 | VOUT | output | Gate drive voltage output. Sources/sinks up to 5.0 A peak (4.0 A minimum) to drive the IGBT/MOSFET gate. |+| 12 | VEE | power_in | Output-side negative supply (typically IGBT emitter-referenced negative rail). Same net as pin 9. |+| 13 | VCC2 | power_in | Positive output supply voltage. Wide VCC operating range 15 to 30 V. |+| 14 | DESAT | input | Desaturation voltage input. When the DESAT voltage exceeds the internal 6.5 V reference while the IGBT is on, FAULT transitions from high impedance to logic low within 5 us and the output performs a soft turn-off. |+| 15 | VLED | passive | LED anode test pin. Must be left unconnected for guaranteed data-sheet performance (used for optical coupling testing only). |+| 16 | VE | power_in | Common IGBT emitter output supply reference (Kelvin-emitter return for the gate driver output stage). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Lite On |+| Package | SOP-16 |+| Category | Optoisolators |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `LTV-333J-TA1-B`+- `LTV-333J-TA1-B-V`+- `LTV-333J-TA1-B-TP1`+- `LTV-333J-TA1-B-TP1-V`++## CAD (KiCad official)++- Symbol: `LTV-333J-TA1-B`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Lite On datasheet](docs/ltv-333j-ta1-b-datasheet.pdf) (19 pp, sha256 `a5d61c26708689bb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
