# NSI8241W0-DSWR

**NOVOSENSE** · Digital Isolators · SOP-16

NSI8241W0-DSWR from NOVOSENSE, in a SOP-16. 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 (supply range 2.5V to 5.5V). |
| 2 | GND1 | power_in | Ground 1, the ground reference for isolator side 1. |
| 3 | INA | input | Logic input A. |
| 4 | INB | input | Logic input B. |
| 5 | INC | input | Logic input C. |
| 6 | OUTD | output | Logic output D (channel D direction is side 2 to side 1 on the NSi8241). |
| 7 | EN1 | input | Output enable 1, active high; when high or NC the side 1 output is enabled, when low it is disabled to high impedance state. |
| 8 | GND1 | power_in | Ground 1, the ground reference for isolator side 1. |
| 9 | GND2 | power_in | Ground 2, the ground reference for isolator side 2. |
| 10 | EN2 | input | Output enable 2, active high; enables the side 2 outputs (by symmetry with EN1, whose table text states high or NC enables and low gives high impedance). |
| 11 | IND | input | Logic input D. |
| 12 | OUTC | output | Logic output C. |
| 13 | OUTB | output | Logic output B. |
| 14 | OUTA | output | Logic output A. |
| 15 | GND2 | power_in | Ground 2, the ground reference for isolator side 2. |
| 16 | VDD2 | power_in | Power supply for isolator side 2 (supply range 2.5V to 5.5V). |
