ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed below may cause permanent
damage to the device. These are stress ratings only. Functional
operation of the device at these or any other conditions greater
than those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

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.
Maximum Duty Cycle

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.

–0.80 +4.10 25%
–0.90 +4.20 15%

ESD
(electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid
performance degradation or loss of functionality.
