SMOKE DETECTOR  
WITH INTERCONNECT  
The A5354CA is a low-current, CMOS circuit providing all of the  
required features for an ionization-type smoke detector. A networking  
capability allows as many as 125 units to be interconnected so that if  
any unit senses smoke, all units will sound an alarm. In addition,  
special features are incorporated to facilitate alignment and test of the  
finished smoke detector. This device is designed to comply with  
Underwriters Laboratories Specification UL217.

TIMING  
The internal oscillator and timing circuitry keeps standby power to  
a minimum by powering down the device for 1.66 seconds and sensing  
smoke for only 10 ms. Every 24 on/off cycles, a check is made for low  
battery condition. By substituting other types of sensors, or a switch  
for the ionization detector, this very-low power device can be used in  
numerous other battery-operated safety/security applications.

The A5354CA is supplied in a low-cost, 16-pin dual in-line plastic  
package. It is rated for continuous operation over the temperature  
range of 0°C to +50°C. Similar devices, with an internal timer to allow  
for a period of reduced sensitivity (“hush”), are available as the  
A5348CA.
