ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at T A = 25°C, V DD1 = V ISO = 3.3 V, V SEL = GND ISO . Minimum/maximum specifications apply over the entire
recommended operation range which is 3.0 V ≤ V DD1 , V SEL , V ISO ≤ 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.
