HT6221 - Multi-Purpose Encoders
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), res
