8 / 24 page ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 Data Sheet ELECTRICAL CHARACTERISTICS—VDD1 = 2.5 V, VDD2 = 3.3 V OPERATION All typical specifications are at TA = 25°C, VDD1 = 2.5, and VDD2 = 3.3 V.Minimum/maximum specifications apply over the entire recommended operating range of 2.25 V ≤ VDD1 ≤ 2.75 V, 3.0 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. For dc specifications and ac specifications, see Table 6 for Side 1 and see Table 3 for Side 2.
