ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = VISO = 3.3 V, VSEL = GNDISO. Minimum/maximum specifications apply over the entire
recommended operation range which is 3.0 V ≤ VDD1, 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.

1 7Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the
isolation barrier.
2 Opposing directional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the
isolation barrier.
