(1) Refer to RETS139AX for LM139A military specifications and to RETS139X for LM139 military specifications.
(2) 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 25°C).
(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 VDC (at
25°C).
(4) 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-N and LM139-N 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 (PD≤100 mW), provided the output transistors are
allowed to saturate.
(5) 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+.

7 Detailed Description
7.1 Overview
The LM139/LM239/LM339 family of devices is a monolithic quad of independently functioning comparators
designed to meet the needs for a medium-speed, TTL compatible comparator for industrial applications. 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 kΩreduces 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 25°C). 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).

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 βof 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-ΩRSAT 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.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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 –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', 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.

9 Power Supply Recommendations
Even in low-frequency applications, the LM139-N can have internal transients which are extremely quick. For this
reason, bypassing the power supply with 1.0 µF 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.
