UM3561

UM3561 Bowin Microelectronics _________________________________________________________ UM3561A 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 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.
