Deciphering the deluge of data

Electronic equipment designers use the part manufacturers´ data sheets to help select parts. To do so efficiently and effectively, designers must understand the data sheet and the constraints part manufacturers place on the use of their parts. Although equipment designers are not necessarily bound by those constraints, they must be aware of them in order to avoid misinterpretation. This article provides a primer on the contents of an electronic data sheet, focusing on the environmental and operational constraints as well as electrical parameters in the context of their relationship with specification limits. The purpose is to make the reader aware of the issues that must be considered in using electronic part data sheets
