Notes:

2. See Switching Test Circuit for test conditions.

3. 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.

4. Skew testing takes into account pattern and switching direction differences between outputs that have equal loading.

may alter these values therefore, minimum values are recommended for simulation purposes only.
