Notes:
1. See “Switching Test Circuit” for test conditions.
2. These parameters are not 100% tested, but are evaluated at initial characterization and at any time
the design is modified where frequency may be affected.
3. 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_S.
