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.
