Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional. These ratings do not guarantee specific performance limits, however. For guaranteed specifications and test conditions, see the Electrical Characteristics. 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
) at any pin exceeds the power supply rails (V
<
GND or V
>
V
+
) 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
,
θ
and the ambient temperature, T
. The maximum
allowable power dissipation at any temperature is P
D
= (T
JMAX
T
A
)/
θ
JA
or the number given in the Absolute Maximum Ratings, whichever is lower. In most cases,
the maximum derated power dissipation will be reached only during fault conditions. For these devices, T
JMAX
for a board-mounted device can be found from the
tables below:

Note 5:
Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 6:
See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in a current National Semicon-
ductor Linear Data Book for other methods of soldering surface mount devices.
Note 7:
Typicals are at +25C and represent must likely parametric norm.
