description/ordering information
The LM111, LM211, and LM311 are single high-speed voltage comparators. These devices are designed to
operate from a wide range of power-supply 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

†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 af fect device reliability.
NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC–.
2. Differential voltages are at IN+ with respect to IN–.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or ±15 V, whichever is less.
4. The output may be shorted to ground or either power supply.
5. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
6. The package thermal impedance is calculated in accordance with JESD 51-7.
7. Maximum power dissipation is a function of TJ(max), θJC, and TC. The maximum allowable power dissipation at any allowable case
temperature is PD = (TJ(max) – TC)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
8. The package thermal impedance is calculated in accordance with MIL-STD-883.

‡All typical values are at TA = 25°C.
NOTES: 9. The offset voltages and of fset 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.
10. The strobe should not be shorted to ground; it should be current driven at –3 mA to –5 mA (see Figures 13 and 27).

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability 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)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
