Note 1
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is
functional These ratings do not guarantee specific performance limits however For guaranteed specifications and test conditions see the Electrical Characteris-
tics The guaranteed specifications apply only for the test conditions listed Some performance characteristics may degrade when the device is not operated under
the listed test conditons
Note 2
All voltages are measured with respect to GND unless otherwise specified
Note 3
When the input voltage (V
IN
) at any pin exceeds the power supply rails (V
IN
k
GND or V
IN
l
V
a
) the absolute value of current at that pin should be limited
to 5 mA or less The 20 mA package input current limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four
Note 4
The maximum power dissipation must be derated at elevated temperatures and is dictated by T

and the ambient temperature T
A
The maximum
allowable power dissipation at any temperature is P

cases the maximum derated power dissipation will be reached only during fault conditions For these devices T
