NSI8220N1-DSPR

NOVOSENSE · Digital Isolators · SOP-8

NSI8220N1-DSPR from NOVOSENSE, in a SOP-8. 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.
