Notes:
1. Value reflects minimum load. The delay is measured from the CCC output to the clock pin of a sequential element
2. Value reflects maximum load. The delay is measured on the clock pin of the farthest sequential element located in a
3. For the derating values at specific junction temperature and voltage supply levels, refer to
