FUNCTIONAL DESCRIPTION
The DEI1041 is a BICMOS device which contains one ARINC 429 differential line receiver. It translates incoming ARINC
429 data bus signals (tri-level RZ bipolar differential modulation) to a pair of TTL/CMOS logic outputs. It meets the
requirements of the ARINC 429 Digital Information Transfer Standard. Refer to Figure 1 “ DEI1041 Block Diagram and
Truth Table”.
The device is designed to operate in a high noise environment. Inputs are accepted over a +/- 20V common mode voltage
range and the receivers provide over 2 Volts of hysteresis. Circuit speed is optimized to reject high frequency transients.
All ARINC input pins are designed with internal protection from damage due to transients meeting the lightning induced
transient requirements of DO-160D Level A3. The ARINC inputs may optionally be connected to ARINC bus through
external 10k ohm series resistors. These resistors may be added in combination with transient voltage suppressors to achieve
lighting protection beyond the Level A3 limits due to high input impedance.
The DEI1041 device provides logic level TEST inputs for built in system test. They force the receiver outputs to the specified
ZERO, ONE or NULL state. The ARINC inputs are ignored when the device is in test mode.
