SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = VSEL = VISO = 5 V. Minimum/maximum specifications apply over the entire recommended
operation range which is 4.5 V ≤ VDD1, 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.
