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.
