DESCRIPTION
The LM139 series consists of four independent precision voltage comparators with an offset voltage specification
as low as 2 mV max for all four comparators. These 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 operated
from a single power supply voltage.
The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and
minus power supplies, they will 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 VDCbelow
the 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 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).
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 and LM139 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.
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+.

Application Hints
The LM139 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 via stray capacitance. This shows up only
during the output voltage transition intervals as the comparator changes states. Power supply bypassing is not
required to solve this problem. Standard PC board layout is helpful as it reduces stray input-output coupling.
Reducing this 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. 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.
All pins of any unused comparators should be tied to the negative supply.
The bias network of the LM139 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.
It is usually unnecessary to use a bypass capacitor across the power supply line.
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 LM139 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 pull-up 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 pull-up resistor is not used). 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 60Ω RSAT of the output transistor. The low offset voltage of the output transistor (1 mV) allows the
output to clamp essentially to ground level for small load currents.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
