DEI1072A-SMS-G
The DEI107xA is a family of 8 pin bipolar integrated circuit line drivers which directly drive the ARINC 429 avionics serial digital data bus. These ARINC 429 Line Drivers convert TTL/CMOS serial input data to the “Trilevel RZ bipolar differential modulation format” of the ARINC bus. The output slew rate is selectable for HI speed (100KBS) or LOW speed (12.5KBS) operation. No external timing capacitors are required.
Features
- TTL/CMOS to ARINC 429 Line Driver

- Pin for pin replacements with the HI8585 and HI8586
Attributes
Functional Description The DEI107xA is a family of 8 pin bipolar integrated circuit line drivers which directly drive the ARINC 429 avionics serial digital data bus. These ARINC 429 Line Drivers convert TTL/CMOS serial input data to the “Trilevel RZ bipolar differential modulation format” of the ARINC bus. The output slew rate is selectable for HI speed (100KBS) or LOW speed (12.5KBS) operation. No external timing capacitors are required. The DEI107xA Line Driver family is an improved version of the popular DEI107x family. It provides:
- Lower power consumption
- Excellent waveform fidelity
- Improved transient immunity. This improvement simplifies the equipment design for lightning and RF immunity requirements.
This new Line Driver family provides options for various output resistor values and output tri-state capability. There are three output resistor options: 0 Ohm, 10 Ohm and 37 Ohm. The 0 Ohm and 10 Ohm versions require external resistors to achieve the 37 Ohm output resistance of the ARINC 429 standard. The external resistors are normally used to simplify the external transient voltage protection network. The outputs are tri-state capable on the 1073/4/5 versions. This feature is useful in non-standard applications where there are multiple drivers on a wire pair.
