简单介绍：
MC145018 MC145018P是离子型烟雾报警芯片，MC145018 MC145018P的封装形式为DIP16,在上海图一网站的资料下载栏目中有MC145018 MC145018P的PDF格式的DataSheet资料和其他技术文档下载。
详情介绍：

The MC145018, when used with an ionization chamber and a small number
of external components, will detect smoke. When smoke is sensed, an alarm is
sounded via an external piezoelectric transducer and internal drivers. This circuit
is designed to operate in smoke detector systems that comply with UL217 and
UL268 specifications.
