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.
The HT6220A/HT6221A/HT6221B/HT6222A contain
30keys (K1~K20, K33~K34, K37~K38, K41~K42,
