IC Music chip-Christmas tunes


These music ICs will drive a speaker through a simple transistor amplifier. application.                        The UM66T series is a CMOS LSI designed melody generator IC for use in telephones and toys application. It has an on-chip ROM programmed for musical performance. Produced by CMOS technology, the device results in very low power consumption. And with built-in RC oscillator, a compact melody module can be constructed with only a few additional components. Absolute Maximum Ratings DC Supply Voltage ..-0.3V to +5.0V Operating Ambient Temperature ..-10°C to 60°C Storage Temperature .-55°C to 125°C
