ELECTRICAL CHARACTERISTICS—3.3 V OPERATION
All typical specifications are at T
A
= 25°C, V
DD1
= V
DD2
= 3.3 V. Minimum/maximum specifications apply over the entire recommended
operation range of 3.0 V ≤ V
DD1
≤ 3.6 V, 3.0 V ≤ V
DD2
≤ 3.6 V, and −40°C ≤ T
A
≤ +105°C, unless otherwise noted. Switching specifications
are tested with C
L
= 15 pF and CMOS signal levels, unless otherwise noted.

that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.

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.
3
Opposing directional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposite sides of the
isolation barrier.
