General Description

The devices are CMOS LSI encoders designed for use

in remote control systems. They are capable of encod-

ing 16-bit address codes and 8-bit data codes. Each ad-

dress/data input can be set to one of the two logic

states, 0 and 1.

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 trig-

gered, the programmed address/data is transmitted to-

gether with the header bits via an IR (38kHz carrier)

transmission medium.

The HT6220A/HT6221A/HT6221B/HT6222A contain

30keys (K1~K20, K33~K34, K37~K38, K41~K42,
