1. See “Switching Test Circuit” for test conditions.
2. Output delay minimums for t_PD, t_CO, t_PZX, t_PXZ, t_EA, and t_ER are defined under best case conditions. Future process improvements
may alter these values; therefore, minimum values are recommended for simulation purposes only.
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_S.
