These comparators 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 characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage. 1 * * * * * * * * Wide Supply Voltage Range LM139/139A Series 2 to 36 VDC or 1 to 18 VDC LM2901-N: 2 to 36 VDC or 1 to 18 VDC LM3302-N: 2 to 28 VDC or 1 to 14 VDC Very Low Supply Current Drain (0.8 mA) -- Independent of Supply Voltage Low Input Biasing Current: 25 nA Low Input Offset Current: 5 nA Offset Voltage: 3 mV Input Common-Mode Voltage Range Includes GND Differential Input Voltage Range Equal to the Power Supply Voltage Low Output Saturation Voltage: 250 mV at 4 mA Output Voltage Compatible With TTL, DTL, ECL, MOS, and CMOS Logic Systems Advantages: - 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 Operation The LMx39-N series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the devices directly interface with MOS logic-- where the low power drain of the LM339 is a distinct advantage over standard comparators.

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 VDC (or 0.3 VDC below the magnitude of the negative power supply, if used) (at 25C). 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 VDC (at 25C). For operating at high temperatures, the LM339/LM339A, LM2901, LM3302 must be derated based on a 125C maximum junction temperature and a thermal resistance of 95C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM239-N and LM139-N must be derated based on a 150C maximum junction temperature. The low bias dissipation and the "ON-OFF" characteristic of the outputs keeps the chip dissipation very small (PD100 mW), provided the output transistors are allowed 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 Ratings V(ESD) (1) 4 Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) VALUE UNIT 600 V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

Since no 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 VCC . The output is an uncommitted collector so it may be used with a pullup resistor and a separate 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 to 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 the OFF state. Power dissipation with all four comparators in the OFF state is typically 4 mW from a single 5-V supply (1 mW/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 the output lead is inadvertently allowed to capacitively couple to the inputs through stray capacitance. This shows up only during the output voltage transition intervals as the comparator changes states. Reducing the input resistors to < 10 k 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. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required. 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 VDC (at 25C). An input clamp diode can be used as shown in the applications section. 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 Submit Documentation Feedback Copyright (c) 1999-2014, Texas Instruments Incorporated Product Folder Links: LM139-N LM239-N LM2901-N LM3302-N LM339-N LM139-N, LM239-N, LM2901-N, LM3302-N, LM339-N www.ti.com SNOSBJ3E - NOVEMBER 1999 - REVISED DECEMBER 2014 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 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- RSAT of the output transistor. The low offset voltage of the output transistor (4 mV) allows the output to clamp essentially to ground level for small load currents. 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 commonly referred to as the "reference" or "VREF" input. All pins of any unused comparators should be tied to the negative supply. The bias network of the LMx39-N series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2 VDC to 30 VDC.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 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 -55C to 125C. While it may seem like a comparator has a well-defined and somewhat limited functionality as a '1-bit ADC', a comparator is a versatile component which can be used for many functions. Refer to AN-74 LM139/LM239/LM339 A Quad of Independently Functioning Comparators (SNOA654) for additional application information on use of the LM139-N. 8.2 Typical Applications 8.2.1 Basic Comparator Figure 11. Basic Comparator Schematic 8.2.1.1 Design Requirements The basic usage of a comparator is to indicate when a specific analog signal has exceeded some predefined threshold. In this application, the negative input is tied to a reference voltage, and the positive input is connected to the input signal. The output is pulled up with a resistor to the logic supply voltage, V+. For an example application, the supply voltage is 5 V. The input signal varies between 1 V and 3 V, and we want to know when the input exceeds 2.5 V. For this example, we would set the VREF to 2.5 V. 8.2.1.2 Application Curve Figure 12.

For this reason, bypassing the power supply with 1.0 F to ground will provide improved performance; the supply bypass capacitor should be placed as close as possible to the supply pin and have a solid connection to ground. The bypass capacitors should have a low ESR. 10 Layout 10.1 Layout Guidelines Try to minimize parasitic impedances on the inputs to avoid oscillation. 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 lead to oscillations on the output. 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 device as possible minimizing strays. 10.2 Layout Example Figure 38.
