Maximum Allowed Overshoot and Undershoot Voltage
During transitions, input signals may overshoot to the voltage listed in Table 2–2 and
undershoot to -2.0 V for input currents less than 100 mA and periods shorter than
20 ns.
Table 2–2 lists the maximum allowed input overshoot voltage and the duration of the
overshoot voltage as a percentage of device lifetime. The maximum allowed
overshoot duration is specified as a percentage of high time over the lifetime of the
device. A DC signal is equivalent to 100% duty cycle. For example, a signal that
overshoots to 3.95 V can only be at 3.95 V for ~5% over the lifetime of the device; for a
device lifetime of 10 years, this amounts to half a year.
