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

on the IC chip. This transistor action can cause the output voltages of the comparators 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.
Note 4:
These specifications are limited to −55˚C≤T
A
≤+125˚C,
for the LM193/LM193A. With the LM293 all temperature specifications are limited to
−25˚C≤T
A
≤+85˚C
and the LM393 temperature specifications are limited to 0˚C≤T
A
≤+70˚C.
The LM2903 is limited to −40˚C≤T
A
≤+85˚C.
Note 5:
The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so
no loading change exists on the reference or input lines.
Note 6:
The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode
voltage range is V
+
−1.5V at 25˚C, but either or both inputs can go to 36V without damage, independent of the magnitude of V
+
.
Note 7:
The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance
characteristics section.
Note 8:
Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the
comparator will provide a proper output state. The low input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply,
if used).
