  RE46C317/18
  Piezoelectric Horn Driver with Boost Converter
  Features: Description: The RE46C317/18 are CMOS piezoelectric horn driver
  ICs with built-in boost converter. They are intended for
  use in 3V battery or battery-backed applications. The
  circuits feature a boost converter and a driver circuit
  suitable for driving a piezoelectric horn. 3V Operation
  Low Quiescent Current
  10V Boost Converter
  Low Horn Driver On-Resistance
  Compatible with RE46C117 The RE46C317/18 are compatible with the RE46C117
  device and offer lower standby current. Applications: The RE46C317 has three valid states of Horn Enable
  (tri-state, low and high), while the RE46C318 has only
  two valid states, low and high. Smoke Detectors
