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.

2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF

capacitor discharged through a 1.5K

Ω resistor into each pin.
