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

All typical specifications are at TA = 25°C, VDDP = VISO = 3.3 V, VSEL resistor network: R1 = 10 kΩ, R2 = 16.9 kΩ. Minimum/maximum

specifications apply over the entire recommended operation range which is 3.0 V ≤ VDDP, VSEL, VISO ≤ 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.
