VIx = VDDx, VCM = 1000 V,

transient magnitude = 800 V

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

falling common-mode voltage edges.

ELECTRICAL CHARACTERISTICS—3 V OPERATION (WA, WB, AND WC GRADES)

All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.0 V. Minimum/maximum specifications apply over the entire recommended operation

range: 3.0 V ≤ VDD1 ≤ 3.6 V, 3.0 V ≤ VDD2 ≤ 3.6 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.
