This document provides information on dual comparator integrated circuits from ON Semiconductor, including the LM393, LM393E, LM293, LM2903, LM2903E, LM2903V, and NCV2903. It includes specifications for electrical characteristics like input offset voltage, input bias current, output saturation voltage, and supply current. The document also provides application information with examples of using the comparators in zero crossing detectors, oscillators, time delay generators, and with hysteresis. Diagrams show typical comparator schematics and markings.
