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
