Description
The HK527 is an integrated circuit, compact and versatile, created specifically for Ding Dong Door Chime applications. Equipped with 8 pins, this IC offers dual-tone sound effects, producing the classic "Ding-Dong" chime. Perfect for doorbells, toys, clock melodies, key chains, and security systems. Users can select either a single "Ding-Dong" or a double "Ding-Dong" sound output by utilizing the OPTION pin. The HK527 is pre-set to produce a double "Ding-Dong" sound.
Triggered by a one-shot re-trigger mode on the TG pin, this circuit ensures reliable performance.
