Melody IC

The CF1156 series are CMOS melody LSIs with built-in LED Driver that, together with a battery and piezo- electric buzzer, operate in one of 3 melody modes determined by input level or bonding options. They also fea- ture an Oscillator stop function in non-play mode and a variable pull-down resistance function that responds to input levels in order to reduce power consumption, reduce cost, and extend battery life, making them ideal in a wide range of applications including greeting cards and toys.
