Product Summary
The HT6221 is a kind of CMOS LSI encoder designed for use in remote control systems. It is capable of encoding 16-bit address codes and 8-bit data codes. Each address/data input can be set to one of the two logic states,0 and 1. The HT6221 contains 32 keys(K1-K32). When one of the keys is triggered,the programmed address/data is transmitted together with the header bits via an IR(38kHz carrier)transmission medium. The HT6221 is ideal for: television and video cassette recorder controllers, burglar alarm systems, smoke and fire alarm systems, garage door controllers, car door controllers, car alarm systems, security systems and other remote control systems.
