    A Subsidiary of Microchip Technology Inc. RE46C141
    CMOS Photoelectric Smoke Detector ASIC with Interconnect
    Product Specification General Description Features The RE46C141 is low power CMOS photoelectric type
    smoke detector IC. With minimal external components
    this circuit will provide all the required features for a
    photoelectric type smoke detector. The design incorporates a gain selectable photo
    amplifier for use with an infrared emitter/detector pair.
    An internal oscillator strobes power to the smoke
    detection circuitry for 100us every 8.1 seconds to keep
    standby current to a minimum. If smoke is sensed the
    detection rate is increased to verify an alarm condition.
    A high gain mode is available for push button chamber
    testing. Internal Power On Reset
    Low Quiescent Current Consumption
    Available in 16L PDIP, 16L N SOIC or 16L W SOIC
    ESD Protection on all Pins
    Interconnect up to 40 Detectors
    Temporal Horn Pattern
    Low Battery and Chamber Test
    Compatible with Motorola MC145012
    UL Recognized per File S24036
    Available in Standard Packaging or RoHS ...
