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, 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 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.

² Stresses beyond those listed under ªabsolute maximum ratingsº 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 ªrecommended operating conditionsº 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.

² Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and the emitter output grounded. Full range for LM111 is ± 55°C to 125°C, for LM211 is ± 40°C to 85°C, and for LM311 is 0°C to 70°C.

³ All typical values are at TA = 25°C.

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 kΩ 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).
