Features
- • •• Four sounds can be selected • Power on reset.
- Typical 3V operating voltage • A magnetic speaker can be driven by connecting
- 8-pin DIP package form an NPN transistor General 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. The M3561 contains a programmed mask ROM to simulate siren sound. Absolute Maximum Ratings
