description/ordering information
The LM211 is a single high-speed voltage comparator. This device is 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. This comparator is 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 wired-OR connected. If the strobe is low, the output is in the off state, regardless of the differential
input.

† 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. The package thermal impedance is calculated in accordance with JESD 51-7.

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