Electrical Characteristics
Table 5
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% of the duty cycle. For example, a signal that
overshoots to 3.95 V can be at 3.95 V for only ~21% over the lifetime of the device; for
a device lifetime of 10 years, the overshoot duration amounts to ~2 years.
