Note 1:
For operating at high temperatures, the LM393 and LM2903 must be derated based on a 125˚C maximum junction temperature and a thermal resistance
of 170˚C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM193/LM193A/LM293 must be derated based on
a 150˚C maximum junction temperature. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation very small (P
D
≤100
mW),
provided the output transistors are allowed to saturate.
Note 2:
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 20 mA independent of the magnitude of V
+
.
Note 3:
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
