11 / 21 page Data Sheet ADuM230D/ADuM230E/ADuM231D/ADuM231E Rev. A | Page 11 of 21 DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS These isolators are suitable for reinforced electrical isolation only within the safety limit data. Protective circuits ensure the maintenance of the safety data. The * marking on packages denotes DIN V VDE V 0884-10 approval. Table 14.
