VALUE
Supply voltage, VCC1 and VCC2
2.25 V to 5.5 V
Decoupling capacitor between VCC1 and GND1
0.1 µF
Decoupling capacitor from VCC2 and GND2
0.1 µF
9.2.2 Detailed Design Procedure
Unlike optocouplers, which require external components to improve performance, provide bias, or limit current,
the ISO772x devices only require two external bypass capacitors to operate.
