1 IOx is the Channel x output current, where x is A or B.
2 VIxH is the input side logic high.
3 VIxL is the input side logic low.
4 VI is the voltage input.
5 N0 refers to the ADuM220N0/ADuM221N0/ADuM225N0/ADuM226N0 models, and N1 refers to the ADuM220N1/ADuM221N1/ADuM225N1/ADuM226N1 models. See
the Ordering Guide section.
6 |CMH| is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDDx. |CML| is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO > 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
