LM139/LM239/LM339/LM2901/LM3302
Low Power Low Offset Voltage Quad Comparators
General Description
The LM139 series consists of four independent precision
voltage comparators with an offset voltage specification as
low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply
over a wide range of voltages. Operation from split power
supplies is also possible and the low power supply current
drain is independent of the magnitude of the power supply
voltage. These comparatorsalso have a unique characteristic in that the input common-mode voltage range includes
ground, even though operated from a single power supply
voltage.
Application areas include limit comparators, simple analog to
digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators
and high voltage digital logic gates. The LM139 series was
designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, they will directly interface with MOS logic— where the low power drain
of the LM339 is a distinct advantage over standard comparators.

Note 4: For operating at high temperatures, the LM339/LM339A,LM2901,LM3302mustbederatedbased 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 and LM139 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
mW), provided the output transistors are allowed to saturate.
Note 5: Short circuits from the output to V
current is approximately 20 mA independent of the magnitude of V
Note 6: 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
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 V
Note 7: These specifications are limited to −55˚C≤T
−25˚C≤T
Note 8: 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 outputso
no loading change exists on the reference or input lines.
Note 9: 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
Note 10: The response time specified is a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance char-
acteristics section.
Note 11: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the com-
parator will provide a proper output state. The low input voltage state must not be less than −0.3 V
if used) (at 25˚C).
