NOTE: Stresses above those listed under "Absolute Maximum Ratings" 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 specifi cation is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
These parameters are sampled, not 100% tested.
NOTE: DC test conditions: VIL = 0.3V, VIH = Vcc -0.3V
