NOTES:
1. In no case may control input signals (e.g., SS) be operated with pulse widths less than the minimum clock input pulse width specifications
(e.g., tKHKL) or at frequencies that exceed the applied K clock frequency.
2. This parameter is sampled and not 100% tested.
3. Measured at ± 200 mV from steady state.
