HOLTEK HT6221/HT6222 Multi-Purpose Encoders Manual

Update: 01 October, 2023

HT6221/HT6222 Multi-Purpose Encoders 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 programmed address/data is transmitted together with the header bits via an IR (38kHz carrier) transmission medium.
