Voltage comparator LM111/211/311/ _LM311B
LM111 series voltage comparators that have input currents approximately hundred times lower than devices like (iA710. They designed operate over wider range supply voltages; from standard supplies down single supply. Their output compatible with RTL, DTL, well circuits. Further, they drive tamps relays, switching voltages currents high 50mA.
Both inputs outputs LM111 series isolated from system ground, output drive loads referred ground, positive supply, negative supply. Offset balancing strobe capability provided outputs wire-ORed.
Although slower than |iA710 (200ns response time 40ns), devices also much less prone spurious oscillations. LM111 series same configuration (iA710 series.

These specifications apply unless otherwise specified. With LM211, however, temperature specifications limited LM111 limited offset voltage, offset current bias current specifications apply supply voltage from single supply supplies.
