DESCRIPTION
The LM111 series are voltage comparators that have input currents
approximately a hundred times lower than devices like the
A710.
They are designed to operate over a wider range of supply voltages;
from standard
15 V op amp supplies down to a single 3 V 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 50 V 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
A710 (200 ns response time versus 40 ns),
the devices are also much less prone to spurious oscillations. The
LM111 series has the same pin configuration as the
A710 series.

supply up to
15 V 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 1 mA
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 100 mV input step with 5 mV over-drive.
5. Do not short the strobe pin to ground; it should be current driven at 3 mA to 5 mA.
6. LM311B, all parameters are at V+ = 3 V
10%; V = GND = 0 V.
