Notes:

9.

High-frequency AC parameters are guaranteed by design and characterization.

10. Within device skew is measured between two different outputs under identical input transitions.

11. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective

inputs.

12. Set-up and hold times apply to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous applications,

set-up and hold times do not apply.
