NSI8140W0

NOVOSENSE · Digital Isolators · SOIC-16-300mil

NSI8140W0 from NOVOSENSE, in a SOIC-16-300mil. 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 from 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND1 required close to the package.
2 GND1 power_in Ground 1, the ground reference for isolator side 1.
3 INA input Logic input A on side 1, with VIH minimum 2 V and VIL maximum 0.8 V.
4 INB input Logic input B on side 1, with VIH minimum 2 V and VIL maximum 0.8 V.
5 INC input Logic input C on side 1, with VIH minimum 2 V and VIL maximum 0.8 V.
6 IND input Logic input D on side 1, with VIH minimum 2 V and VIL maximum 0.8 V.
7 NC/EN1 input Output enable 1, an active high logic input; when EN1 is low the side 1 outputs go to high impedance, and when EN1 is high or the pin is not connected the side 1 outputs are enabled.
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, an active high logic input; when EN2 is low the side 2 outputs are disabled to high impedance, and when EN2 is high or the pin is not connected they are enabled.
11 OUTD output Logic output D, with VOH minimum VDD-0.3 V at IOH = -4 mA and VOL maximum 0.3 V at IOL = 4 mA.
12 OUTC output Logic output C, with VOH minimum VDD-0.3 V at IOH = -4 mA and VOL maximum 0.3 V at IOL = 4 mA.
13 OUTB output Logic output B, with VOH minimum VDD-0.3 V at IOH = -4 mA and VOL maximum 0.3 V at IOL = 4 mA.
14 OUTA output Logic output A, with VOH minimum VDD-0.3 V at IOH = -4 mA and VOL maximum 0.3 V at IOL = 4 mA.
15 GND2 power_in Ground 2, the ground reference for isolator side 2.
16 VDD2 power_in Power supply for isolator side 2, specified from 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND2 required close to the package.

CAD (KiCad official)

  • Symbol: NSI8140W0
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16-300mil (KiCad packages3D, STEP)
  • 3D model files: nsi8140w0-etched.step / nsi8140w0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nsi8140w0.step / nsi8140w0.glb are the bare package body.
