Technical Data

Low-Power CMOS

Ionization Smoke Detector IC

MC14467-1

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.
