LM139-N,LM239-N,LM2901-N,LM3302-N,LM339-N SNOSBJ3E–NOVEMBER1999–REVISEDDECEMBER2014 www.ti.com 7 Detailed Description 7.1 Overview The LM139/LM239/LM339 family of devices is a monolithic quad of independently functioning comparators designedtomeettheneedsforamedium-speed,TTLcompatiblecomparatorforindustrialapplications.Sinceno antisaturation clamps are used on the output such as a Baker clamp or other active circuitry, the output leakage current in the OFF state is typically 0.1 nA. This makes the device ideal for system applications where it is desired to switch a node to ground while leaving it totally unaffected in the OFF state. Other features include single supply, low voltage operation with an input common mode range from ground up to approximately one volt below V . The output is an uncommitted collector so it may be used with a pullup resistor and a separate CC output 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 device tobeusedinwired-ORconfigurations,suchasawindowcomparators. In addition it may be used as a single pole switch to ground, leaving the switched node unaffected while in the OFF state. Power dissipation with all four comparators in the OFF state is typically 4 mW from a single 5-V supply(1mW/comparator). 7.2 Functional Block Diagram 7.3 Feature Description The LMx39-N series are high-gain, wide bandwidth devices which, like most comparators, can easily oscillate if theoutputleadisinadvertentlyallowedtocapacitivelycoupletotheinputsthroughstraycapacitance.Thisshows up only during the output voltage transition intervals as the comparator changes states. Reducing the input resistors to < 10 kΩ reduces the feedback signal levels and finally, adding even a small amount (1 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible.SimplysocketingtheICandattachingresistorstothepinswillcauseinput-outputoscillationsduringthe small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise andfalltimes,hysteresisisnotrequired. The differential input voltage may be larger than V+ without damaging the device. Protection should be provided to prevent the input voltages from going negative more than −0.3 V (at 25°C). An input clamp diode can be DC usedasshownintheapplicationssection. The output of the LMx39-N series is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR'ing function. An output pullup resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V+ terminal of the LM139A package. The output can also be used as a simple SPST switch to ground (when a pullup resistor is not used). 10 SubmitDocumentationFeedback Copyright©1999–2014,TexasInstrumentsIncorporated ProductFolderLinks:LM139-N LM239-N LM2901-N LM3302-N LM339-N

LM139-N,LM239-N,LM2901-N,LM3302-N,LM339-N www.ti.com SNOSBJ3E–NOVEMBER1999–REVISEDDECEMBER2014 Feature Description (continued) The amount of current which the output device can sink is limited by the drive available (which is independent of V+) and the β of this device. When the maximum current limit is reached (approximately 16 mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60-Ω R of the output transistor. The low offset voltage of the output transistor (4 SAT mV)allowstheoutputtoclampessentiallytogroundlevelforsmallloadcurrents. 7.4 Device Functional Modes A basic comparator circuit is used for converting analog signals to a digital output. The output is HIGH when the voltage on the non-inverting (+IN) input is greater than the inverting (-IN) input. The output is LOW when the voltage on the noninverting (+IN) input is less than the inverting (-IN) input. The inverting input (-IN) is also commonlyreferredtoasthe"reference"or"VREF"input. Allpinsofanyunusedcomparatorsshouldbetiedtothenegativesupply. The bias network of the LMx39-N series establishes a drain current which is independent of the magnitude of the powersupplyvoltageovertherangeoffrom2V to30V .

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The LM139-N is specified for operation from 2.0 V to 36 V (±1V to ±18V) over the temperature range of –55°C to 125°C. While it may seem like a comparator has a well-defined and somewhat limited functionality as a '1-bit ADC',acomparatorisaversatilecomponentwhichcanbeusedformanyfunctions.

BasicComparatorSchematic 8.2.1.1 DesignRequirements The basic usage of a comparator is to indicate when a specific analog signal has exceeded some predefined threshold.

Any positive feedback used as hysteresis should place the feedback components as close as possible to the input pins. Take care to ensure that the output pins do not couple to the inputs. This can occur through capacitive coupling if the traces are too close and leadtooscillationsontheoutput. The optimum bypass capacitor placement is closest to the V+ and ground pins. Take care to minimize the loop area formed by the bypass capacitor connection between V+ and ground. The ground pin should be connected to the PCB ground plane at the pin of the device. The feedback components should be placed as close to the deviceaspossibleminimizingstrays. 10.2 Layout Example Figure38.

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
