FEATURES
  • The ARINC 429 MULTI-BIT DECODER from Applied Avionics can provide a full binary decode for up to three bits from a single ARINC 429 data label
  • The 2 X 4 decoder  option is available in an 8-pin package (expandable to 12-pin) while the 3 X 8 decoder  is a 12-pin device
  • The polarity of the decoded outputs is selectable (one selection for all decoded results)
  • The ARINC converter circuitry inside the ARINC 429 MULTI-BIT DECODER includes an internal Health Monitor that can provide a “fail” indication if power to the decoder is lost or upon loss of valid ARINC data input
  • The Health Monitor has a range of watchdog timings requiring a valid ARINC label to be received within a specified time interval
  • If specified, the Health Monitor can be selected as a decoder input
  • This device is part of our NEXSYS Component Technology and is configurable inside of a VIVISUN switch/annunciator or a NEXSYS Module
  • When used in a VIVISUN switch/annunciator, the compact size of the decoder allows for the inclusion of additional NEXSYS components or electro-mechanical switch poles
  • The ARINC 429 MULTI-BIT DECODER is designed, tested and qualified to applicable military standards
  • Two specified ARINC data bits are input to the 2 X 4 decoder producing four binary results on four separate output pins
  • Output polarity for the decoded bits can be specified as Open = True or Ground = True
  •  Within the same 8-pin package, repurpose decoder answer “00,” “11” or both with discrete bits, including the internal Health Monitor
  •  By increasing to a 12-pin package, all four decoder answers can remain accessible and two additional discrete outputs can be added, including the internal Health Monitor
  •  Three specified ARINC data bits are input to the 3 X 8 decoder producing eight binary results on eight separate output pins. Output polarity for the decoded bits can be specified as Open = True or Ground = True
  •  Within the same 12-pin package, repurpose decoder answer “000,” “111” or both with discrete bits, including the internal Health Monitor
  • The ARINC 429 MULTIBIT DECODER also meets the environmental requirements of DO-160

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
