UM3561 - UM3561A Three Siren Sound Generator

Datasheet Summary

Description

UM3561 is a low-cost, low-power CMOS LSI designed for use in alarm and toy applications.

Since the integrated circuit includes oscillator and selector circuits, a compact sound module can be constructed with only a few additional components.

Features

  • Four sounds can be selected.
  • Typical 3V operating voltage.
  • 8-pin DIP package form.
  • Power on reset.
  • A magnetic speaker can be driven by connecting an NPN transistor General.
