a. The maximum continuous supply voltage is 4.8V. Brief spikes above this 4.8V can be tolerated. Specifically,
voltages as high as 5.5V for up to 10 seconds cumulative duration over the lifetime of the device are allowed.
Voltages as high as 5.0V for up to 250 seconds cumulative duration over the lifetime of the device are allowed.
