Caution! ESD sensitive device.

Exceeding any one or a combination of the Absolute Maximum Rating conditions may

cause permanent damage to the device. Extended application of Absolute Maximum

Rating conditions to the device may reduce device reliability. Specified typical perfor-

mance or functional operation of the device under Absolute Maximum Rating condi-

tions is not implied.
