•
•
•
The LM111, LM211, and LM311 devices are single
high-speed voltage comparators. These devices are
designed to operate from a wide range of powersupply voltages, including ±15-V supplies for
operational amplifiers and 5-V supplies for logic
systems. The output levels are compatible with most
TTL and MOS circuits. These comparators are
capable of driving lamps or relays and switching
voltages up to 50 V at 50 mA. All inputs and outputs
can be isolated from system ground. The outputs can
drive loads referenced to ground, VCC+ or VCC−. Offset
balancing and strobe capabilities are available, and
the outputs can be wire-OR connected. If the strobe
is low, the output is in the off state, regardless of the
differential input.

Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded. Full range for
LM111 is –55°C to 125°C, for LM211 is –40°C to 85°C, for LM211Q is –40°C to 125°C, and for LM311 is 0°C to 70°C.
All typical values are at TA = 25°C.
The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to 1 V
with a pullup resistor of 7.5 kΩ to VCC+. These parameters actually define an error band and take into account the worst-case effects of
voltage gain and input impedance.
The strobe must not be shorted to ground; it must be current driven at –3 mA to –5 mA (see Figure 18 and Figure 31).

8 Detailed Description
8.1 Overview
The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower
than legacy standard devices. They are also designed to operate over a wider range of supply voltages: from
standard ±15V op amp supplies down to the single 5-V supply used for IC logic. Their output is compatible with
RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50
V at currents as high as 50 mA.
Both the inputs and the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the
output can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and strobe
capability are provided and outputs can be wire ORed. The LM211 is identical to the LM111, except that its
performance is specified over a −25°C to +85°C temperature range instead of −55°C to +125°C. The LM311 has
a temperature range of 0°C to +70°C.

8.3 Feature Description
LMx11 consists of a PNP input stage to sense voltages near VCC–. It also contains balance and strobe pins for
external offset adjustment or trimming.
The input stage is followed by a very high gain stage for very fast response after a voltage difference on the input
pins have been sensed.

Feature Description (continued)
This is then followed by the output stage that consists of an open collector NPN (pulldown or low-side) transistor.
Unlike most open drain comparators, this NPN output stage has an isolated emitter from VCC–, allowing this
device to set the VOL output value for collector output.
8.4 Device Functional Modes
8.4.1 Voltage Comparison
The LMx11 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.

9 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.
9.1 Application Information
A typical LMx11 application compares a single signal to a reference or two signals against each other. 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 LMx11 optimal for level shifting to
a higher or lower voltage.

9.2.2 Detailed Design Procedure
When using LMx11 in a general comparator application, determine the following:
• Input voltage range
• Minimum overdrive voltage
• Output and drive current
• Response time
9.2.2.1 Input Voltage Range
When choosing the input voltage range, consider the input common mode voltage range (VICR). Operation
outside of this range can yield incorrect comparisons.
The following list describes the outcomes of some input voltage situations.

SLCS007I – SEPTEMBER 1973 – REVISED JUNE 2015
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 undefined
9.2.2.2 Minimum Overdrive Voltage
Overdrive voltage is the differential voltage produced between the positive and negative inputs of the comparator
over the offset voltage (VIO). In order 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 14 and Figure 15 show positive
and negative response times with respect to overdrive voltage.
9.2.2.3 Output and Drive Current
Output current is determined by the pullup resistance and pullup voltage. The output current produces a output
low voltage (VOL) from the comparator, in which VOL is proportional to the output current. Use Figure 5 to
determine VOL based on the output current.
The output current can also effect the transient response.
9.2.2.4 Response Time
The load capacitance (CL), pullup resistance (RPULLUP), and equivalent collector-emitter resistance (RCE) levels
determine the transient response. Equation 1 approximates the positive response time. Equation 2 approximates
the negative response time. RCE can be determine by taking the slope of Figure 5 in the linear region at the
desired temperature, or by Equation 3.

10 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.
11 Layout
11.1 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).

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

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.
