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

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.
