MC145017  
Low-Power CMOS  
Ionization Smoke Detector IC  
with Temporal Pattern Horn Driver  
LOW-POWER CMOS IONIZATION  
SMOKE DETECTOR IC WITH  
TEMPORAL PATTERN  
HORN DRIVER  
The MC145017, 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.
