ELECTRICAL CHARACTERISTICS—3.3 V OPERATION

All typical specifications are at T_A= 25°C, V_DD1= V_DD2= 3.3 V. Minimum/maximum specifications apply over the entire recommended

operation range of 3.0 V ≤ V_DD1≤ 3.6 V, 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.

¹t_PSKis the magnitude of the worst-case difference in t_PHLor t_PLHthat is measured between units at the same operating temperature, supply voltages, and output load

within the recommended operating conditions.

²Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier.

³Opposing directional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposite sides of the

isolation barrier.
