Note:
1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified where
capacitance may be affected.
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. t
CF
is a calculated value and is not guaranteed. t
CF
can be found using the following equation:
t
CF
= 1/f
MAX
(internal feedback) - t
