These comparators were designedspecifically to operate from a single power supplyover a wide range of voltages. Operation from splitpower supplies is also possible and the low powersupply current drain is independent of the magnitudeof the power supply voltage. These comparators alsohave a unique characteristic in that the inputcommon-mode voltage range includes ground, eventhough they are operated from a single power supplyvoltage.1 Wide Supply Voltage RangeLM139/139A Series 2 to 36 VDC or 1 to 18 VDCLM2901-N: 2 to 36 VDC or 1 to 18 VDCLM3302-N: 2 to 28 VDC or 1 to 14 VDCVery Low Supply Current Drain (0.8 mA) —Independent of Supply VoltageLow Input Biasing Current: 25 nALow Input Offset Current: 5 nAOffset Voltage: 3 mVInput Common-Mode Voltage Range IncludesGNDDifferential Input Voltage Range Equal to thePower Supply VoltageLow Output Saturation Voltage: 250 mV at 4 mAOutput Voltage Compatible With TTL, DTL, ECL,MOS, and CMOS Logic SystemsAdvantages:– High-Precision Comparators– Reduced VOS Drift Overtemperature– Eliminates Need for Dual Supplies– Allows Sensing Near GND– Compatible With All Forms of Logic– Power Drain Suitable for Battery OperationThe LMx39-N series was designed to directlyinterface with TTL and CMOS.

As long as the other voltage remains within the common-moderange, 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 belowthe magnitude of the negative power supply, if used) (at 25 C).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 ofthe input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there isalso lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to goto the V voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructiveand normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than 0.3 VDC (at25 C).For operating at high temperatures, the LM339/LM339A, LM2901, LM3302 must be derated based on a 125 C maximum junctiontemperature and a thermal resistance of 95 C/W which applies for the device soldered in a printed circuit board, operating in a still airambient. The LM239-N and LM139-N must be derated based on a 150 C maximum junction temperature. The low bias dissipation andthe “ON-OFF” characteristic of the outputs keeps the chip dissipation very small (PD 100 mW), provided the output transistors areallowed to saturate.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 .6.2 ESD RatingsV(ESD)(1)4Electrostatic dischargeHuman-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1)VALUEUNIT 600VJEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.Submit Documentation FeedbackCopyright 1999–2014, Texas Instruments IncorporatedProduct Folder Links: LM139-N LM239-N LM2901-N LM3302-N LM339-N

Since noantisaturation clamps are used on the output such as a Baker clamp or other active circuitry, the output leakagecurrent in the OFF state is typically 0.1 nA. This makes the device ideal for system applications where it isdesired to switch a node to ground while leaving it totally unaffected in the OFF state. Other features includesingle supply, low voltage operation with an input common mode range from ground up to approximately one voltbelow VCC . The output is an uncommitted collector so it may be used with a pullup resistor and a separateoutput supply to give switching levels from any voltage up to 36V down to a V CE SAT above ground(approximately 100 mV), sinking currents up to 16 mA. The open collector output configuration allows the deviceto be used in wired-OR configurations, such as a window comparators.In addition it may be used as a single pole switch to ground, leaving the switched node unaffected while in theOFF state. Power dissipation with all four comparators in the OFF state is typically 4 mW from a single 5-Vsupply (1 mW/comparator).7.2 Functional Block Diagram7.3 Feature DescriptionThe LMx39-N series are high-gain, wide bandwidth devices which, like most comparators, can easily oscillate ifthe output lead is inadvertently allowed to capacitively
