SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION (ALL GRADES)
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V. Minimum/maximum specifications apply over the entire recommended operation
range: 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V, −40°C ≤ TA ≤ 125°C, unless otherwise noted. Switching specifications are tested with CL = 15 pF
and CMOS signal levels, unless otherwise noted.

1 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. Opposing-direction 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.
