ELM339 - INFRARED REMOTE CONTROL

General Description

The ELM339 is a complete remote control decoder in an 8 pin package.

With the addition of a standard infrared receiver module, three individual outputs can be simultaneously controlled using a television remote control transmitter.

Key Features

  • Low power CMOS design - typically 1mA at 5V.
  • Three separate outputs.
  • Pulse output for momentary controls.
  • Signal received output for visual feedback.
  • Easy interface to standard receiver modules.
  • Works with universal TV remote transmitters.
  • High current drive outputs - up to 25 mA Connection Diagram PDIP and SOIC (top view) VDD 1 Out5 2 Out7 3 Pulse7 4 8 VSS 7 Out3 6 LED 5 IRRx Block Diagram IRRx 5 Data Decoder LED 6 Output Dr.

ELM339 Infrared Remote Control Description The ELM339 is a complete remote control decoder in an 8 pin package. With the addition of a standard infrared receiver module, three individual outputs can be simultaneously controlled using a television remote control transmitter. This circuit responds to Sony™ television control codes, chosen because most universal remotes default to them when initially powered up. The ELM339 continuously monitors the stream of data from an infrared receiver module looking for these Sony type remote control codes. If an appropriate three digit code is detected, the selected output either turns on, turns off, or switches its state. One of the outputs can be configured to provide a 250msec pulse output, if desired.
