LM139/LM239/LM339/LM2901/LM3302Low Power Low Offset Voltage Quad ComparatorsGeneral DescriptionFeaturesThe LM139 series consists of four independent precisionvoltage comparators with an offset voltage specification aslow as 2 mV max for all four comparators. These weredesigned specifically to operate from a single power supplyover a wide range of voltages. Operation from split powersupplies is also possible and the low power supply currentdrain is independent of the magnitude of the power supplyvoltage. These comparators also have a uniquecharacteristic in that the input common-mode voltage rangeincludes ground, even though operated from a single powersupply voltage.Application areas include limit comparators, simple analog todigital converters; pulse, squarewave and time delaygenerators; wide range VCO; MOS clock timers;multivibrators and high voltage digital logic gates. TheLM139 series was designed to directly interface with TTLand CMOS. When operated from both plus and minus powersupplies, they will directly interface with MOS logic — wherethe low power drain of the LM339 is a distinct advantageover standard comparators.nnnnnnnnnnnnWide supply voltage rangeLM139/139A Series2 to 36 VDCor 1 to 18 VDCLM2901:2 to 36 VDCor 1 to 18 VDCLM3302:2 to 28 VDCor 1 to 14 VDCVery low supply current drain (0.8 mA) — independentof supply voltageLow input biasing current:25 nA 5 nALow input offset current: 3 mVOffset voltage:Input common-mode voltage range includes GNDDifferential input voltage range equal to the powersupply voltageLow output saturation voltage:250 mV at 4 mAOutput voltage compatible with TTL, DTL, ECL, MOSand CMOS logic systemsAdvantagesnnnnnnHigh precision comparatorsReduced VOS drift over temperatureEliminates need for dual suppliesAllows sensing near GNDCompatible with all forms of logicPower drain suitable for battery operationOne-Shot Multivibrator with Input Lock OutDS005706-12 2001 National Semiconductor 39/LM2901/LM3302 Low Power Low Offset Voltage Quad ComparatorsAugust 2000

The LM239 and LM139 must be deratedbased 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.Note 2: Short circuits from the output to V can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum outputcurrent 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 PNPtransistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor actionon 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 timeduration 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 returnsto a value greater than 0.3 VDC (at 25 )C.Note 4: These specifications are limited to 55 C TA 125 C, for the LM139/LM139A. With the LM239/LM239A, all temperature specifications are limited to 25 C TA 85 C, the LM339/LM339A temperature specifications are limited to 0 C TA 70 C, and the LM2901, LM3302 temperature range is 40 C TA 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 sono 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-modevoltage range is V 1.5V at 25 C, but either or both inputs can go to 30 VDC 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 performancecharacteristics 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, thecomparator will provide a proper output state. The low input voltage state must not be less than 0.3 VDC (or 0.3 VDCbelow the magnitude of the negative powersupply, if used) (at 25 C).Note 9: At output switch point, VO.1.4 VDC, RS 0Ω with V from 5 VDC to 30 VDC; and over the full input common-mode range (0 VDC to V 1.5 VDC), at 25 C.For LM3302, V from 5 VDC to 28 VDC.Note 10: Refer to RETS139AX for LM139A military specifications and to RETS139X for LM139 military specifications.www.national.com4

Protection should be provided toprevent the input voltages from going negative more than 0.3 VDC (at 25 C). An input clamp diode can be used asshown in the applications section.The output of the LM139 series is the uncommitted collectorof a grounded-emitter NPN output transistor. Many collectorscan be tied together to provide an output OR’ing function. Anoutput pull-up resistor can be connected to any availablepower supply voltage within the permitted supply voltagerange and there is no restriction on this voltage due to themagnitude of the voltage which is applied to the V terminalof the LM139A package. The output can also be used as asimple SPST switch to ground (when a pull-up resistor is notused). The amount of current which the output device cansink is limited by the drive available (which is independent ofV ) and the β of this device. When the maximum current limitis reached (approximately 16 mA), the output transistor willcome out of saturation and the output voltage will rise veryrapidly. The output saturation voltage is limited by theapproximately 60Ω RSAT of the output transistor. The lowoffset voltage of the output transistor (1 mV) allows theoutput to clamp essentially to ground level for small loadcurrents.The LM139 series are high gain, wide bandwidth deviceswhich, like most comparators, can easily oscillate if theoutput lead is inadvertently allowed to capacitively couple tothe inputs via stray capacitance. This shows up only duringthe output voltage transition intervals as the comparatorchanges states. Power supply bypassing is not required tosolve this problem. Standard PC board layout is helpful as itreduces stray input-output coupling. Reducing this inputresistors to 10 kΩ reduces the feedback signal levels andfinally, adding even a small amount (1 to 10 mV) of positivefeedback (hysteresis) causes such a rapid transition thatoscillations due to stray feedback are not possible. Simplysocketing the IC and attaching resistors to the pins will causeinput-output oscillations during the small transition intervalsunless hysteresis is used. If the input signal is a pulsewaveform, with relatively fast rise and fall times, hysteresis isnot required.All pins of any unused comparators should be tied to thenegative supply.The bias network of the LM139 series establishes a draincurrent which is independent of the magnitude of the powersupply voltage over the range of from 2 VDC to 30 VDC.It is usually unnecessary to use a bypass capacitor acrossthe power supply line.Typical ApplicationsBasic Comparator(V 5.0 VDC)Driving CMOSDriving TTLDS005706-3DS005706-5DS005706-4www.national.com6
