... ADuM3440/ADuM3441/ADuM3442 APPLICATION INFORMATION PC BOARD LAYOUT The ADuM344x digital isolator requires no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (Figure 16). Bypass capacitors are most conveniently connected between Pin 1 and Pin 2 for V and between Pin 15 and ...

... ADuM3440/ADuM3441/ADuM3442 INSULATION LIFETIME All insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. The rate of insulation degradation is dependent on the characteristics of the voltage waveform applied across the insulation. In addition to the testing performed by the regulatory agencies, Analog Devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the ADuM344x ...
