ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 19 may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

1 _{Applies only when VDDEXT is within specifications. When VDDEXT is outside speci-}
fications, the range is V_DDEXT ± 0.2 V.
2 _{Applies to 5 V tolerant pins SCL, SDA, and PJ4. For duty cycles, see Table 20.}

1 _{Applies to all signal pins with the exception of CLKIN, XTAL, and VROUT1–0.}
2 _{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.
3 _{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.

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.
