MC14468 Description
Freescale Semiconductor Technical Data Low-Power CMOS Ionization Smoke Detector IC with Interconnect The MC14468, when used with an ionization chamber and a small number of external ponents, 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 ply with UL217 and UL268...
