¹I_Oxis the Channel x output current, where x is A or B.

²V_IxHis the input side logic high.

³V_IxLis the input side logic low.

⁴V_Iis the voltage input.

⁵N0 refers to the ADuM220N0/ADuM221N0/ADuM225N0/ADuM226N0 models, and N1 refers to the ADuM220N1/ADuM221N1/ADuM225N1/ADuM226N1 models. See

the Ordering Guide section.

⁶|CM_H| is the maximum common-mode voltage slew rate that can be sustained while maintaining V_O> 0.8 V_DDx. |CM_L| is the maximum common-mode voltage slew rate

that can be sustained while maintaining V_O> 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
