Maximum Allowed Overshoot or Undershoot Voltage

During transitions, input signals may overshoot to the voltage listed in Table 1–2 and

undershoot to –2.0 V for a magnitude of currents less than 100 mA and for periods

shorter than 20 ns. Table 1–2 lists the maximum allowed input overshoot voltage and

the duration of the overshoot voltage as a percentage over the lifetime of the device.

The maximum allowed overshoot duration is specified as percentage of high-time

over the lifetime of the device.

4.2 V can only be at 4.2 V for 10.74% over the lifetime of the device; for device lifetime

of 10 years, this amounts to 10.74/10ths of a year.
