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.
5. Output delay minimums for tPD, tCO, tPZX, tPXZ, tEA, and tER are defined under best case conditions. Future process improvements
may alter these values therefore, minimum values are recommended for simulation purposes only.
6. tCF is a calculated value and is not guaranteed. tCF can be found using the following equation:
tCF = 1/fMAX (internal feedback) – tS.
