UM3561 Three Siren Sound Generator
_____________________________________________________________________________
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 Description
The M3561 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. The M3561 contains a programmed mask ROM to simulate siren
sound.
