Low–Power CMOS
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.

* Maximum Ratings are those values beyond which damage to the device may occur.
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal
precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation
it is recommended that except for pin 8, V
