... The ADuM524x digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins as shown in Figure 8. For the ADuM5240 and ADuM5241, a bypass capacitance (C ensure proper power-up. For all models bypass capacitance is recommended with the isolated side ...
