SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY
4.5 V ≤ VDD1 ≤ 5.5 V, VSEL = VISO; each voltage is relative to its respective ground. All minimum/maximum specifications apply over the
entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 5.0 V, VISO = 5.0 V, and
VSEL = VISO.
