7 / 20 page ADuM3210/ADuM3211 Rev. C | Page 7 of 20 ELECTRICAL CHARACTERISTICS—5 V, 125°C OPERATION All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V. Minimum/maximum specifications apply over the entire recommended operation range: 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 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. Table 13.
