SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V. Minimum/maximum specifications apply over the entire recommended
operation range of 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 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.

Codirectional channel matchin
g
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-directional channel matching is th
e
absolute value
of the
difference in propagation delays between any two channels with inputs on opposin
g
sides of the isolation barrier.

1 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD. The common-mode voltage slew rates apply to both
rising and falling common-mode voltage edges.
