一、使用前需进行了解在使用集成电路IC之前,应对所用IC的基本功能特点、主要参数、各引脚功能和典型应用电路作全面的了解,这样做可以消除使用中的盲目性,为正确使用打下良好的基础。对于集成度较高,内部电路结构复杂的IC,在初次使用时要着重了解其各引脚功能和主要参数,这样往往会事半功倍,如果在使用之后再来深究IC的内部电路结构和工作原理,就会比较容易了。二、正确识别引脚和空脚处置由于各类IC众多,封装形式繁杂,即使同类封装的IC引脚排序也不相同。因此在使用前需仔细识别引脚的排序,以防止接错或反向插入插座,致使电路
First, understand before using In the use of integrated circuit IC, the IC should be used to deal with the basic features, the main parameters, the pin function and the typical application circuit for a comprehensive understanding of doing so can eliminate the blindness in use, to be correct Use to lay a good foundation. For high integration, the internal structure of the complex circuit IC, when used for the first time to focus on understanding its pin function and the main parameters, so often with less effort, if after using the IC and then look into the internal circuit structure and working principle It will be easier. Second, the correct identification of pins and empty feet due to the large number of various types of IC packaging complexity, even if the same package IC pin ordering is not the same. Therefore, prior to use the pin to be carefully identified sort order to prevent the wrong or reversed inserted into the socket, causing the circuit
