SPECIFICATIONS

ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY

All typical specifications are at TA = 25°C, VDDP = VISO = 5 V, VSEL resistor network: R1 = 10 kΩ, R2 = 30.9 kΩ. Minimum/maximum

specifications apply over the entire recommended operation range which is 4.5 V ≤ VDDP, VSEL, VISO ≤ 5.5 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.
