Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • Inputs are accepted over a +/- 20 V common mode voltage range and the receivers provide over 2 Volts of hysteresis.
  • Circuit speed is optimized to reject high frequency transients.
  • The DEI1049 is equivalent to the DEI1046A product, but with 40 k Ω of the input resistors removed so the part will operate with external 40 kΩ resistors.
  • The DEI1049 ARINC inputs must be connected to the ARINC bus through 40 kΩ series resistors for correct operation.
  • The 40 kΩ resistors limit surge current and thus minimize the power requirement and size of the TVS.
  • DS-MW-01049-01 Rev B 01/08/2019 ELECTRICAL DESCRIPTION Table 2: Absolute Maximum Rating PARAMETER MIN MAX UNITS Supply Voltage (with respect to VSS) -0.3 7.0 V Storage Temperature -65 +150 °C Input Voltage, continuous (ARINC Inputs) 115 Va.
  • Inputs withstand 1500 V Waveform 5A when clipped ≤ 600 V.

  • FEATURES
  • ORDERING INFORMATION

Engineering review checklist

  • Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
  • Derate continuous power for ambient temperature and verify pulse or surge capability separately.
  • Match the land pattern, termination finish and current-sense routing to the exact package option.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
