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 | VDD1 | power_in | Power supply for isolator Side 1. Operating range 2.5 V to 5.5 V (absolute max 6.5 V). Decouple to GND1 with a local bypass capacitor. |+| 2 | INA | input | Logic input for channel A on Side 1. VIH ≥ 2 V, VIL ≤ 0.8 V. Internal pull is 8 uA (typ) high or low depending on the default-output option. |+| 3 | INB | input | Logic input for channel B on Side 1. VIH ≥ 2 V, VIL ≤ 0.8 V. On NSi8220 both INA and INB are on Side 1 (Side1 → Side2 for both channels). |+| 4 | GND1 | power_in | Ground reference for isolator Side 1. Return for VDD1 and for INA/INB logic levels. |+| 5 | GND2 | power_in | Ground reference for isolator Side 2. Return for VDD2 and for OUTA/OUTB logic levels. Galvanically isolated from GND1. |+| 6 | OUTB | output | Logic output for channel B on Side 2. VOH ≥ VDD2 − 0.4 V and VOL ≤ 0.4 V at IO ≤ 4 mA. Output impedance ~50 Ω. |+| 7 | OUTA | output | Logic output for channel A on Side 2. VOH ≥ VDD2 − 0.4 V and VOL ≤ 0.4 V at IO ≤ 4 mA. Output impedance ~50 Ω. |+| 8 | VDD2 | power_in | Power supply for isolator Side 2. Operating range 2.5 V to 5.5 V (absolute max 6.5 V). Decouple to GND2 with a local bypass capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | NOVOSENSE |+| Package | SOP-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `NSi8220N1-DSPR`+- `NSi8221N1-DSPR`+- `NSi8222N1-DSPR`+- `NSi8220Wx-DSWVR`+- `NSi8221Wx-DSWVR`+- `NSi8222Wx-DSWVR`+- `NSi8220Wx-DSWR`+- `NSi8221Wx-DSWR`+- `NSi8222Wx-DSWR`++## CAD (KiCad official)++- Symbol: `NSI8220N1-DSPR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [NOVOSENSE datasheet](docs/nsi8220n1-dspr-datasheet.pdf) (31 pp, sha256 `a44b95fb4fbf6bb2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
