5368

    The A5368CA 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 of A5368CA areincorporated to facilitate alignment and test of the finished smoke detector.  This A5368CA is designed to comply with Underwriters Laboratories Specification UL217.

    The internal oscillator and timing circuitry keeps standby power to a minimum by powering down the A5368CA 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  ubstituting other types of sensors, or a switch for the ionization detector, this A5368CA very-low power device can be used in numerous other battery-operated safety/security applications.

    The A5368CA 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.
