(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 under recommended operating
conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2)
All voltage values are with respect to network ground terminal.
(3)
The human body model is a 100pF capacitor discharged through a 1.5k
Ω resistor into each pin. The machine model is a 200pF
capacitor discharged directly into each pin.
