HT6221B规格书详情
General Description
The devices 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 HT6220A/HT6221A/HT6221B/HT6222A contain 30keys (K1~K20, K33~K34, K37~K38, K41~K42, K45~K46, K49~K50), 32 keys (K1~K32), 48 keys (K1~K32, K33~K34, K37~K38, K41~K42, K45~K46, K49~K50, K53~K54, K57~K58, K61~K62) and 64 keys (K1~K64), respectively. When one of the keys is triggered, the programmed address/data is transmitted to gether with the header bits via an IR (38kHz carrier) transmission medium.
