		Maximum Duty
VIN Max (V)1	VIN Min (V)1	Cycle2
+3.63	–0.33	100%
+3.64	–0.34	90%
+3.70	–0.40	50%
+3.78	–0.48	30%
+3.86	–0.56	17%
+3.93	–0.63	10%

1The individual values cannot be combined for analysis of a single instance of overshoot or undershoot. The worst case observed value must fall within one of the voltages specified and the total duration of the overshoot or undershoot (exceeding the 100% case) must be less than or equal to the corresponding duty cycle.

2Duty cycle refers to the percentage of time the signal exceeds the value for the 100% case. This is equivalent to the measured duration of a single instance of overshoot or undershoot as a percentage of the period of occurrence. The practical worst case for period of occurrence for either overshoot or undershoot is 2 × tSCLK.
