general notes on timing parameters

All output signals from the 2401A device (including CLKOUT) are derived from an internal clock such that all

output transitions for a given half-cycle occur with a minimum of skewing relative to each other.

The signal combinations shown in the following timing diagrams may not necessarily represent actual cycles.

For actual cycle examples, refer to the appropriate cycle description section of this data sheet.
