HT6221A Datasheet - Holtek Semiconductor

HT6221A (HT6220A - HT6222A) Multi-Purpose Encoders

The devices 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 HT6220A/HT6221A/HT6222A contain 30keys (K1~K16, K17~K20, K33~K34, K37~.
