Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2:
Human body model, 1.5 k
in series with 100 pF. Machine model, 200
in series with 100 pF.
Note 3:
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150C. Output currents in excess of 45 mA over long term may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T
J(max)
,
θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is

Note 5:
Typical Values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
