SWITCHING CHARACTERISTICS OVER COMMERCIAL OPERATING RANGES
Notes:
1. See “Switching Test Circuit” for test conditions.
2. Output delay minimums for t
3. Skew testing takes into account pattern and switching direction differences between outputs that have equal loading.
4. These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified where
