ADuM4400W/ADuM4401W/ADuM4402W
ELECTRICAL CHARACTERISTICS—MIXED 5 V/3.3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = 5 V, V DD2 = 3.3 V. Minimum/maximum specifications apply over the entire recommended
operation range: 4.5 V ≤ VDD1 ≤ 5.5 V, 3.135 V ≤ VDD2 ≤ 3.6 V, and −40°C ≤ TA ≤ 125°C, unless otherwise noted. Switching specifications
are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.

1 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VOx > 0.8 VDD. The common-mode voltage slew rates apply to both
rising and falling common-mode voltage edges.
