ADuM3210/ADuM3211

ELECTRICAL CHARACTERISTICS—MIXED 5 V/3 V, 105°C OPERATION

All typical specifications are at T_A= 25°C, V_DD1= 5 V, V_DD2= 3.0 V. Minimum/maximum specifications apply over the entire

recommended operation range: ADuM3210 supply voltages 4.5 V ≤ V_DD1≤ 5.5V, 2.7 V ≤ V_DD2≤ 3.6 V; ADuM3211 supply voltages

4.5 V ≤ V_DD1≤ 5.5V, 3.0 V ≤ V_DD2≤ 3.6 V, and −40°C ≤ T_A≤ +105°C, unless otherwise noted. Switching specifications are tested with

C_L= 15 pF, and CMOS signal levels, unless otherwise noted.
