4 / 16 page ADuM7240/ADuM7241 Data Sheet Rev. A | Page 4 of 16 ELECTRICAL CHARACTERISTICS—3.3 V OPERATION All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.3 V. Minimum/maximum specifications apply over the entire recommended operation range of 3.0 V ≤ VDD1 ≤ 3.6 V, 3.0 V ≤ VDD2 ≤ 3.6 V, and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted. Table 4.
