UM3561 Three siren sound generator

UM3561 Three Siren Sound Generator IC with 4 Selectable Sounds

The UM3561 is an integrated circuit designed to generate multiple siren sounds. This low-power CMOS LSI integrates both oscillator and selector circuits. It requires few external components for a compact sound module. An internal programmed mask ROM provides four distinct siren sounds. The device operates typically at 3V. It includes a power-on reset feature for reliable startup. The 8-pin DIP package facilitates integration into standard PCBs.
