LM111, LM211, LM311 are voltage comparators with low input currents. They are designed to operate over a wide range of supply voltages. Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50V at output currents as high as 50mA.
This handbook describes the LM111, LM211, and LM311 voltage comparators, highlighting their low input currents, wide supply voltage range (5 V to 15 V), and output compatibility with RTL‑DTL, TTL, and MOS circuits. It includes ordering information, pin connections, schematic diagrams, and typical application circuits.
Detailed electrical characteristics are given, such as absolute maximum ratings, operating conditions, input offset voltage, bias current, response time, and mechanical package data for both DIP and SO versions. The document also presents characteristic curves, output limiting behavior, and typical performance graphs.
