四款5407系列六缓冲器测试分析

Test Analysis of Four 5407 Series Six Buffer

元器件种类不断增多,同系列产品也日益完善。一般来说同系列产品共用手册,但手册内容有限,不便于设计师选用和更换。为此,开展对四款5407系列六缓冲器的测试分析,明确该类器件的功能性能、关键参数变化、极限评估。设计完成通用数字电路板卡级测试系统,实现通用数字器件板卡级运行状态实时监测,提高器件使用可靠性,验证了测试系统的稳定性和通用性。为器件选用和更换提供依据,为通用数字器件的可靠性分析提供测试方法和手段。

The types of components are constantly increasing,and the products of the same series are also improving day by day. Generally speaking,the same series of products share the manual,but the manual content is limited,which is not convenient for designers to choose and replace. To this end,the test analysis of four 5407 series six buffers is carried out to clarify the functional performance,key parameter changes and limit evaluation of such devices. A general-purpose digital circuit board-level test system is designed to realize real-time monitoring of general-purpose digital device board-level operation status,improve device reliability,and verify the stability and versatility of the test system. It provides basis for device selection and replacement,and provides testing methods and means for reliability analysis of general digital devices.
