1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability
.
2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitor
discharged through a 1.5KΩ resistor into each pin.
