ELECTRICAL CHARACTERISTICS—3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.0 V. Minimum/maximum specifications apply over the entire recommended
operation range: 2.7 V ≤ VDD1 ≤ 3.6 V, 2.7 V ≤ VDD2 ≤ 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. 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.

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.
