UM3561 Siren Sound Generator

31

UM3561 is an excellent ROM IC that can generate Multi siren tones simulating Police siren, Ambulance siren, Fire brigade siren and Machine gun sound. This 8 pin low power IC can work down to 2.4 volts.

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

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. The M3561 contains a programmed mask ROM to simulate siren sound. Absolute Maximum Ratings

  • DC Supply Voltage .......................................... -0.3V to +5.0V
  • Input Voltage Range ...................................... Vss-0.3V to Vdd+0.3V
  • Operating Ambient Temperature .................... -10°C to +60°C
  • Storage Temperature ...................................... -55°C to +125°C

UM3561 is an excellent ROM IC that can generate Multi siren tones simulating Police siren, Ambulance siren, Fire brigade siren and Machine gun sound. This 8 pin low power IC can work down to 2.4 volts.
