description
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 will be in the off state regardless of the
differential input.
The LM111 is characterized for operation over the
full military range of 55
C to 125
C. The LM211
is characterized for operation from 40
C to
85
C, and the LM311 is characterized for
operation from 0
C to 70
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.
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.

NOTES:
5. 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.
6. The strobe should not be shorted to ground; it should be current driven at 3 mA to 5 mA (see Figures 13 and 27).
