UM3561

The UM3561 is a low-cosr,low-power CMOS LSI designed for use in toy applications,since the integrated cricuit includes oscillator and selector circuits,a compact sound module can be constructed with only a few additional components,It contains a programmed mask ROM to simulate siren sounds.

Features of the UM3561 are:(1)four sounds can be selected;(2)typical 3V operating voltage;(3)RC oscillator with an external resistor;(4)a magnetic speaker can be driven by connecting an NPN transistor;(5)power on reset.

The absolute maximum ratings of the UM3561 can be summarized as:(1)DC supply voltage:-0.3V to +5.0V;(2)input/output voltage:VSS-0.3V to VDD+0.3V;(3)operating ambient temperature:-10 to +60;(4)storage temperature:-55 to +125.
