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.
