Notes:
1. See “Switching Test Circuit” for test conditions.
2. Skew is measured with all outputs switching in the same direction.
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. tCF is a calculated value and is not guaranteed. tCF can be found using the following equation:
tCF = 1/fMAX (internal feedback) - tS.
