3 / 28 page  Data Sheet ADuM5401/ADuM5402/ADuM5403/ADuM5404 Rev. B | Page 3 of 28 SPECIFICATIONS ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY 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. Table 2.
