    CMOS Ionization Smoke Detector ASIC with Interconnect and Timer Mode
    Product Specification General Description Features The RE46C122 is low power CMOS ionization type
    smoke detector IC. With few external components this
    circuit will provide all the required features for an
    ionization type smoke detector. An internal oscillator strobes power to the smoke
    detection circuitry for 10.5mS every 1.66 seconds to
    keep standby current to a minimum. A check for a low
    battery condition is performed every 40 seconds when
    in standby. The temporal horn pattern supports the
    NFPA 72 emergency evacuation signal.
    An interconnect pin allows multiple detectors to be
    connected such that when one units alarms all units will
    sound. >1500V ESD Protection (HBM) on all Pins
    Guard Outputs for Ion Detector Input
    +/-0.75pA Detect Input Current
    Internal Reverse Battery Protection
    Low Quiescent Current Consumption (<6.5uA)
    Available in 16L PDIP or 16L N SOIC
    Internal Low Battery Detection
    Power Up Low Battery Test
    Interconnect up to 40 Detectors ...
