1 The 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.
2 Duty 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 × t
