HT6222 -- Multi-Purpose Encoders

General Description

The HT6222 is CMOS LSI encoders designed for use in remote control systems. HT6222capable of encoding 16-bit address codes and 8-bit data codes. HT6222 Each address/data input can be set to one of the two logic states, 0 and 1.
The HT6222 contain 32 keys (K1~K32) and 64 keys (K1~K64), respectively. When one of the keys is triggered, HT6222 programmed address/data is transmitted together with the header bits via an IR (38kHz carrier) transmission medium.
