If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
For operating at high temperatures, the LM358/LM358A, LM2904 must be derated based on a +125°C maximum junction temperature
and a thermal resistance of 120°C/W for PDIP, 182°C/W for TO-99, 189°C/W for SOIC package, and 230°C/W for DSBGA, which
applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM258/LM258A and LM158/LM158A can be
derated based on a +150°C maximum junction temperature. The dissipation is the total of both amplifiers—use external resistors, where
possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit.
Short circuits from the output to V
+
can cause excessive heating and eventual destruction. When considering short circuits to ground,
the maximum output current is approximately 40 mA independent of the magnitude of V
+
. At values of supply voltage in excess of +15V,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result
from simultaneous shorts on all amplifiers.
This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of
the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is
also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to
the V
+
voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and
normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than
−0.3V
(at 25°C).
