HT6222A Datasheet (ht6220a - Ht6222a) Multi-purpose Encoders

Manufacturer: Holtek Semiconductor

Overview: HT6220A/HT6221A/HT6222A Multi-Purpose Encoders.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.
