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, V
CC+
or V
CC
.
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 affect 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),
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) TA)/
JA. 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),
JC, and TC. The maximum allowable power dissipation at any allowable case
temperature is PD = (TJ(max) TC)/
JC. 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.

NOTES:
9. 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 k
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).
