... ADuM7440/ADuM7441/ADuM7442 APPLICATIONS INFORMATION PC BOARD LAYOUT The ADuM744x digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 16). A total of four bypass capacitors should be connected between Pin 1 and Pin 2 for V ...

Page 16
... ADuM7440/ADuM7441/ADuM7442 The insulation lifetime of the ADuM744x depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. Figure 20, Figure 21, and Figure 22 illustrate these different isolation voltage waveforms. Bipolar ac voltage is the most stringent environment. The goal ...
