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 comparators also have a unique characteris-

tic 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 gen-

erators; 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.

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 −0.3 V DC (at 25˚)C.

Note 4: These specifications are limited to −55˚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 outputso

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 +30 V DC without damage (25V for LM3302), independent of the magnitude of V + .

Note 7: 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

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 −0.3 V DC (or 0.3 V DC below the magnitude of the negative power

supply, if used) (at 25˚C).

Note 1: 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 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
