13.1 Absolute Maximum Ratings
Caution! The absolute maximum ratings in
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.

1.
The maximum continuous voltage is 4.8V. 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 5.0V (for up to 250 seconds), cumulative duration over the lifetime of the device, are allowed.
2.
Duration not to exceed 25% of the duty cycle.
