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.

Codirectional 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.
