3 Description
The LM139-MIL device consists of four independent
voltage comparators that are designed to operate
from a single power supply over a wide range of
voltages. Operation from dual supplies also is
possible, as long as the difference between the two
supplies is 2 V to 36 V, and VCC is at least 1.5 V
more positive than the input common-mode voltage.
Current drain is independent of the supply voltage.
The outputs can be connected to other open-collector
outputs to achieve wired-AND relationships.
The LM139-MIL device is characterized for operation
over the full military temperature range of –55°C to
+125°C.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, except differential voltages, are with respect to network ground.
Differential voltages are at xIN+ with respect to xIN–.
Input current flows through parasitic diode to ground and will turn on parasitic transistors that will increase ICC and may cause output to
be incorrect. Normal operation resumes when input is removed.
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.

All characteristics are measured with zero common-mode input voltage, unless otherwise specified.
The voltage at either input or common-mode must not be allowed to go negative by more than 0.3 V. The upper end of the commonmode voltage range is VCC+ – 1.5 V; however, one input can exceed VCC, and the comparator will provide a proper output state as long
as the other input remains in the common-mode range. Either or both inputs can go to 30 V without damage.

7 Detailed Description
7.1 Overview
The LM139-MIL is a quad comparators with the ability to operate up to an absolute maximum of 36 V on the
supply pin. This standard device has proven ubiquity and versatility across a wide range of applications. This is
due to very wide supply voltages range (2 V up to 32 V), low Iq, and fast response of the device.
The open-drain output allows the user to configure the output logic low voltage (VOL) and allows the comparator
to be used in AND functionality.

Figure 6. Schematic (Each Comparator)
7.3 Feature Description
The comparator consists of a PNP Darlington pair input, allowing the device to operate with very high gain and
fast response with minimal input bias current. The input Darlington pair creates a limit on the input commonmode voltage capability, allowing the comparator to accurately function from ground to (VCC – 1.5 V) differential
input. Allow for (VCC – 2 V) at cold temperature.
The output consists of an open-collector NPN (pulldown or low-side) transistor. The output NPN sinks current
when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is
resistive and scales with the output current. See the Specifications section for VOL values with respect to the
output current.
7.4 Device Functional Modes
7.4.1 Voltage Comparison
The comparator operates solely as a voltage comparator, comparing the differential voltage between the positive
and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input
differential polarity.

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. Validate and test
the design implementation to confirm system functionality.
8.1 Application Information
Typically, a comparator compares either a single signal to a reference, or to two different signals. Many users
take advantage of the open-drain output to drive the comparison logic output to a logic voltage level to an MCU
or logic device. The wide supply range and high voltage capability makes the LM139-MIL device optimal for level
shifting to a higher or lower voltage.

8.2.2 Detailed Design Procedure
When using the LM139-MIL in a general comparator application, determine the following:
• Input voltage range
• Minimum overdrive voltage
• Output and drive current
• Response time
8.2.2.1 Input Voltage Range
When choosing the input voltage range, the input common-mode voltage range (VICR) must be taken in to
account. If temperature operation is above or below 25°C the VICR can range from 0 V to VCC– 2 V. This limits
the input voltage range to as high as VCC– 2 V and as low as 0 V. Operation outside of this range can yield
incorrect comparisons.

The following list describes the outcomes of some input voltage situations.
•
•
•
•
When both IN– and IN+ are both within the common-mode range:
– If IN– is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking
current
– If IN– is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is
not conducting
When IN– is higher than common mode and IN+ is within common mode, the output is low and the output
transistor is sinking current
When IN+ is higher than common mode and IN– is within common mode, the output is high impedance and
the output transistor is not conducting
When IN– and IN+ are both higher than common mode, the output is low and the output transistor is sinking
current
8.2.2.2 Minimum Overdrive Voltage
Overdrive voltage is the differential voltage produced between the positive and negative inputs of the comparator
over the offset voltage (VIO). To make an accurate comparison, the overdrive voltage (VOD) must be higher than
the input offset voltage (VIO). Overdrive voltage can also determine the response time of the comparator, with the
response time decreasing with increasing overdrive. Figure 8 and Figure 9 show positive and negative response
times with respect to overdrive voltage.
8.2.2.3 Output and Drive Current
Output current is determined by the load and pullup resistance and logic and pullup voltage. The output current
produces a low-level output voltage (VOL) from the comparator, where VOL is proportional to the output current.
The output current can also effect the transient response.
8.2.2.4 Response Time
Response time is a function of input over-drive. See the Typical Characteristics graphs for typical response
times. The rise and fall times can be determined by the load capacitance (CL), load/pull-up resistance (RPULLUP)
and equivalent collector-emitter resistance (RCE).
•
•
The rise time (τR) is approximately τR~ RPULLUP × CL
The fall time (τF) is approximately τF ~ RCE × CL
– RCE can be determined by taking the slope of Figure 3 in its linear region at the desired temperature, or by
dividing the VOL by IOUT

9 Power Supply Recommendations
For fast response and comparison applications with noisy or AC inputs, use a bypass capacitor on the supply pin
to reject any variation on the supply voltage. This variation can affect the common-mode range of the comparator
input and create an inaccurate comparison.
10 Layout
10.1 Layout Guidelines
To create an accurate comparator application without hysteresis, maintain a stable power supply with minimized
noise and glitches, which can affect the high level input common-mode voltage range. To achieve this accuracy,
add a bypass capacitor between the supply voltage and ground. Place a bypass capacitor on the positive power
supply and negative supply (if available).
NOTE
If a negative supply is not being used, do not place a capacitor between the GND pin of
the device and system ground.
