3. Codirectional channel-to-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-to-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.

voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range

over which the common mode is slewed.

5. Start-up time is the time period from the application of power to valid data at the output.
