18. tIS and tIH (input setup and hold) derating.
For all input signals the total tIS (setup time) and tIH(hold time) required is calculated by adding the datasheet tIS(base) and tIH(base) value to the delta
tIS and delta tIH derating value respectively. Example: tIS(total setup time)= tIS(base) + delta tIS.
