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.
