Low-Power CMOS
Ionization Smoke Detector IC
The MC14467-1, 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.
