CTR124: 4 bit Address - 12 bit Data Encoder / Decoder


Control124 is a 4 bit address, 12 bit data encoder and decoder combined in a single IC. This device can operate in either Encode or Decode mode. It uses 1kbps differential Manchester bit..



  • Operating voltage (temperature):

    4.0V-5.5V for standard version (-40Deg C to +125Deg C)

    2.0V-5.5V for low voltage version (-40Deg C to +85Deg C)

  • Draws <2mA without external load
  • 4 bit address and 12 bit data
  • 16different remotes with 4 controls each
  • Single packetised transmission for fast activation
  • Maximum usuage of the range capability of an RF module
  • Adequate preamble to settle data slicer in the receiver
  • Extra wake up preamble to allow for transmitter power up time requirements
  • Differential Manchester encoding of address, data and checksum
  • Synchronisation codes and checksum to reduce false triggering on noise
  • Suitable to be used with Narrow Band FM radio modules
  • Ceramic resonator or crystal oscillator up to 20MHz
  • Data rate up to 5.6kbps
  • Minimum external component requirement
  • 4 wire, push button and latched push button modes
  • Custom address, data bit variations available subject to minimum order quantity


  • Security and Alarm systems
