NSI8222N1-DSPR

NOVOSENSE · Digital Isolators · SOP-8

NSI8222N1-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, specified at 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND1 placed as close to the package as possible.
2 INA input Logic input A referenced to GND1; VIH is at least 2 V and VIL at most 0.8 V, and the input must stay between -0.4 V and VDD+0.4 V with an absolute maximum of 6.5 V.
3 OUTB output Logic output B; VOH is at least VDD−0.4 V at IOH ≤ 4 mA and VOL is at most 0.4 V at IOL ≤ 4 mA, with output current limited to ±15 mA absolute maximum.
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 INB input Logic input B; VIH is at least 2 V and VIL at most 0.8 V, and the input must stay between -0.4 V and VDD+0.4 V with an absolute maximum of 6.5 V.
7 OUTA output Logic output A; VOH is at least VDD−0.4 V at IOH ≤ 4 mA and VOL is at most 0.4 V at IOL ≤ 4 mA, with output current limited to ±15 mA absolute maximum.
8 VDD2 power_in Power supply for isolator side 2, specified at 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND2 placed as close to the package as possible.
