**NOVOSENSE** · Digital Isolators · SOP-8

NSI8220N0-DSPR from NOVOSENSE, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Power supply for isolator side 1, with a recommended operating range of 2.5V to 5.5V and a 0.1 µF bypass capacitor required between VDD1 and GND1. |
| 2 | INA | input | Logic input A, with a high level input voltage (VIH) of at least 2V and a low level input voltage (VIL) of at most 0.8V. |
| 3 | INB | input | Logic input B, with a high level input voltage (VIH) of at least 2V and a low level input voltage (VIL) of at most 0.8V. |
| 4 | GND1 | power_in | Ground 1, the ground reference for isolator side 1. |
| 5 | GND2 | power_in | Ground 2, the ground reference for isolator side 2. |
| 6 | OUTB | output | Logic output B, with a high level output voltage (VOH) of VDD-0.4V at IOH ≤ 4mA and a low level output voltage (VOL) of at most 0.4V at IOL ≤ 4mA. |
| 7 | OUTA | output | Logic output A, with a high level output voltage (VOH) of VDD-0.4V at IOH ≤ 4mA and a low level output voltage (VOL) of at most 0.4V at IOL ≤ 4mA. |
| 8 | VDD2 | power_in | Power supply for isolator side 2, with a recommended operating range of 2.5V to 5.5V and a 0.1 µF bypass capacitor required between VDD2 and GND2. |
