Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended 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 (HBM) is 1.5 k
in series with 100 pF.
Note 3:
Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of
the device such that T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where T
J
>
T
A
.
Note 4:
All limits are guaranteed by design or statistical analysis.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
The maximum power dissipation is a function of T
,
θ
and T
. The maximum allowable power dissipation at any ambient temperature is
