Data Sheet

ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY

All typical specifications are at T_A= 25°C, V_DDP= V_ISO= 3.3 V. Minimum and maximum specifications apply over the entire

recommended operation range, which is 3.0 V ≤ V_DDP, V_ISO≤ 3.6 V, and −40°C ≤ T_A≤ +125°C, unless otherwise noted.

ELECTRICAL CHARACTERISTICS—5.0 V OPERATION DIGITAL ISOLATOR CHANNELS ONLY

All typical specifications are at T_A= 25°C, V_DD1= V_DD2= 5.0 V. Minimum and maximum specifications apply over the entire recommended

operation range: 4.5 V ≤ V_DD1, V_DD2≤ 5.5 V, and −40°C ≤ T_A≤ +125°C, unless otherwise noted. Switching specifications are tested with

C_L= 15 pF and CMOS signal levels, unless otherwise noted. Supply currents are specified with 50% duty cycle signals.
