Low-Power CMOS Ionization Smoke
Detector IC with Interconnect
The MC14468, 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.
