IOx is the Channel x output current, where x = A or B.

2

VIxH is the input side logic high voltage.

3

VIxL is the input side logic low voltage.

4

VI is the input voltage.

5

N0 is the ADuM120N0/ADuM121N0 models, and N1 is the ADuM120N1/ADuM121N1 models. See the Ordering Guide.

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.
