1 / 13 page  HT6221/HT6222 Multi-Purpose Encoders Block Diagram 1 March 2, 2000 Features · Operating voltage: 1.8V~3.5V · DOUT with 38kHz carrier for IR medium · Low standby current · Minimum transmission word: one word · 455kHz ceramic resonator or crystal · 16-bit address codes · 8-bit data codes · PPM code method · Three double-active keys · Maximum active keys - HT6221: 32 keys - HT6222: 64 keys · Low power and high noise immunity CMOS technology Applications · Television and video cassette recorder con- trollers · Burglar alarm systems · Smoke and fire alarm systems · Garage door controllers · Car door controllers · Car alarm systems · Security systems · Other remote control systems General Description The HT6221/HT6222 are CMOS LSI encoders designed for use in remote control systems. They are 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/HT6222 contain 32 keys (K1~K32) and 64 keys (K1~K64), respectively. When one of the keys is triggered, the pro- grammed address/data is transmitted together with the header bits via an IR (38kHz carrier) transmission medium.
