11 / 24 page Data Sheet ADuM3440/ADuM3441/ADuM3442 Rev. D | Page 11 of 24 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. Maintenance of the safety data is ensured by protective circuits. The asterisk (*) marking on packages denotes DIN V VDE V 0884-10 approval. Table 7.
