UM3561 Three siren sound generator

UM3561 Three Siren Sound Generator IC with 4 Selectable Sounds

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