    CMOS Ionization Smoke Detector ASIC
    Product Specification General Description Features The RE46C120 is a low power CMOS ionization type
    smoke detector IC. With a 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 TONE input allows for selection of a
    temporal pattern or a 2/3 duty cycle continuous tone.
    The temporal horn pattern supports the NFPA 72
    emergency evacuation signal. Guard Outputs for Ion Detector Input
    +/-0.75pA Detect Input Current
    Internal Reverse Battery Protection
    Internal Low Battery Detection
    Pin Selectable Horn Pattern
    Low Quiescent Current Consumption (<6.5uA)
    16L PDIP
    ESD Protection on all Pins
    Compatible with MC145017, MC14467
    UL Recognized per File S24036 ...
