Product specification
LM111/211/311/
LM311B
DESCRIPTION
The LM111 series are voltage comparators that have input currents
approximately a hundred times lower than devices like the µA710.
They are designed to operate over a wider range of supply voltages;
from standard ±15V op amp supplies down to a single 3V supply.
Their output is compatible with RTL, DTL, and TTL as well as MOS
circuits. Further, they can drive lamps or relays, switching voltages
up to 50V at currents as high as 50mA.
Both the inputs and the outputs of the LM111 series can be isolated
from system ground, and the output can drive loads referred to
ground, the positive supply, or the negative supply. Offset balancing
and strobe capability are provided and outputs can be wire-ORed.
Although slower than the µA710 (200ns response time vs 40ns), the
devices are also much less prone to spurious oscillations. The LM111
series has the same pin configuration as the µA710 series.

NOTES:
1. This rating applies for ±15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30V below the positive supply, whichever is less.
2. These specifications apply for VS=±15V and 0°C < TA < 70°C unless otherwise specified. With the LM211, however, all temperature
specifications are limited to -25°C TA 85°C and for the LM111 is limited to -55°C TA < 125°C. The offset voltage, offset current, and bias
current specifications apply for any supply voltage from a single 5V supply up to ±15V supplies.
3. The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1mA
load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
4. The response time specified is for a 100mV input step with 5mV over-drive.
5. Do not short the strobe pin to ground; it should be current driven at 3mA to 5mA.
6. LM311B, all parameters are at V+ = 3V ±10%, V– = GND = 0V.
