Caution:

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings

only; functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not

implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.

Caution:

Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when

handling and transporting these devices.

The human body model is a 100pF capacitor discharge through a 1.5k

Ω resistor pin. The machine model is a 200pF capacitor discharged directly

into each pin.
