Refer to RETS139AX for LM139A military specifications and to RETS139X for LM139 military specifications.

(2)

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

−0.3 VDC (or 0.3 VDC below

the magnitude of the negative power supply, if used) (at 25°C).

(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

−0.3 VDC (at

25°C).

(4)

For operating at high temperatures, the LM339/LM339A, LM2901, LM3302 must be derated based on a 125°C maximum junction

temperature and a thermal resistance of 95°C/W which applies for the device soldered in a printed circuit board, operating in a still air

ambient. The LM239-N and LM139-N 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 (PD≤100 mW), provided the output transistors are

allowed to saturate.

(5)

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+.
