24V Electrical Characteristics
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 Charactenstics.
Note 2:
Human body model, 1.5kΩ in series with 100pF.
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 150˚C.
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 P
D
=
(T
J(MAX)
− T
A
)/θ
JA
. All numbers apply for packages soldered directly into a PC board.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
For guaranteed military specifications see military datasheet MNLM6142AM-X.
Note 8:
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 the internal self heating where T
