HT6220A Datasheet (ht6220a - Ht6222a) Multi-purpose Encoders

Manufacturer: Holtek Semiconductor

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

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.

Key Features

  • Operating voltage: 2.0V~3.6V.
  • DOUT with 38kHz carrier for IR medium.
  • Low standby current.
  • Minimum transmission word: one word.
  • Build-in RC (Internal RC) oscillator.
  • 16-bit address codes.
  • 8-bit data codes.
  • PPM code method.
  • Three double-active keys.
  • Maximum active keys - HT6220A: 30 keys - HT6221A: 32 keys - HT6222A: 64 keys.
  • Low power and high noise immunity CMOS technology.
  • HT6220A: 16-pin NSOP package HT6221A: 20-pin SOP package HT6.
