Description of product
UM3561 - Three Siren Sound Generator
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.
Features
- Four sounds can be selected
- Power on reset.
- Typical 3V operating voltage
- A magnetic speaker can be driven by connecting
