CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation  
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.  
NOTES:  
1. Destructive latchup may occur if input signals are applied before the power supply is established or if inputs or outputs are forced to  
voltages exceeding V  
or V by 0.3V.
