Level-Detector Integrated Circuit

In recent years, there has been increasing emphasis upon the utilization of integrated circuits (IC´s) to perform many of the basic control functions in circuitry for power equipment. The advantages of this approach accrue from the economic considerations involved with using IC´s in quantities and also the feasibility that a certain amount of standardization of circuitry may be obtained. The subject of this paper is a newly developed IC control module, the level detector, which is intended for use in telephone power systems equipment.
