Notes:
2. See Switching Test Circuit for test conditions.
3. Output delay minimums are measured under best-case conditions.
4. These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified
where frequency may be affected.
5. Skew is measured with all outputs switching in the same direction.
