Timings
Timing Diagram Conventions
This data sheet contains timing diagrams. The following key explains the components used in these diagrams. Any
variations are clearly labelled when they occur. Therefore, no additional meaning should be attached unless
specifically stated.
Timing Conditions
Unless specified otherwise, the following conditions are true for all timing measurements. All characteristics are
specified at V
