Note: Values in this data sheet are design goals and are subject to change based on the results of
device characterization.
Absolute Maximum Ratings
Caution! The absolute maximum ratings in Table 29 indicate levels where permanent damage to the
device can occur, even if these limits are exceeded for only a brief duration. Functional operation is
not guaranteed under these conditions. Operation at absolute maximum conditions for extended
periods can adversely affect long-term reliability of the device.

a. The maximum continuous voltage is 5.25V. Voltage transients up to 6.0V for up to 10 seconds, cumulative
duration over the lifetime of the device, are allowed. Voltage transients as high as 5.5V for up to 250 seconds,
cumulative duration over the lifetime of the device, are allowed.
b. Duration not to exceed 25% of the duty cycle.
