UM66T19LK Melody Generator IC TO-92 Pack of 1000
The UM66T19LK is a compact, low-power melody generator IC housed in a TO-92 package, designed to produce musical tones when powered. It integrates a pre-programmed melody into its memory, making it ideal for applications such as greeting cards, toys, doorbells, and alarm systems. This specific variant, UM66T19LK, plays a fixed melody, delivering clear and pleasant musical notes through a simple external circuit. This IC operates on low voltage (1.5V to 4.5V), making it perfect for battery-powered applications. It has an open collector output, which typically drives a transistor to power a speaker or piezo buzzer. The internal oscillator and melody ROM eliminate the need for external timing components, simplifying circuit design significantly. The UM66T19LK stands out for its ultra-low power consumption, allowing it to be used in long-life and compact devices. It is also cost-effective and easy to implement, making it a favorite among hobbyists and electronic project designers who require sound output without microcontroller complexity.
