Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

The 20-mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input

current of 5 mA to four. Under normal operating conditions the maximum current that pins 2, 4 or 5 can handle is limited to 5 mA each.
