ABOLUTE MAXIMUM RATINGS
*Stresses greater than those listed may cause
permanent damage to the device. This is a stress
rating only, and functional operation of the device
at these or any other conditions above those
indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods
may affect reliability.
