    RE46C191
    CMOS Low-Voltage Photoelectric Smoke Detector ASIC
    with Interconnect and Timer Mode
    Features: General Description: The RE46C191 is a low-power, low-voltage CMOS
    photoelectric-type smoke detector IC. With minimal
    external components, this circuit provides all the
    required features for a photoelectric-type smoke
    detector. Two AA Battery Operation
    Low Quiescent Current Consumption
    Local Alarm Memory
    Interconnect up to 40 Detectors
    Nine-Minute Timer for Sensitivity Control
    Temporal or Continuous Horn Pattern
    Internal Low Battery and Chamber Test
    All-Internal Oscillator
    Internal Infrared Emitter Diode (IRED) Driver
    Adjustable IRED Drive Current
    Adjustable Hush Sensitivity
    Two percent Low Battery Set Point
    Pin-for-Pin Compatible with RE46C190 The design incorporates a gain-selectable photo
    amplifier for use with an infrared emitter/detector pair.
    To keep the standby current to a minimum, an internal
    oscillator strobes power to the smoke detection ...
