• DEI1044 has TTL/CMOS test inputs
Functional Description:
The DEI1044 and DEI1045 are quad ARINC 429 Line Receiver ICs implemented in BICMOS technology. They contain four
differential line receivers. Each receiver channel translates incoming ARINC 429 data bus signals to a pair of TTL/CMOS outputs.
Each receiver operates independently, is lightning protected, and meets all requirements of the ARINC 429 Digital Information
Transfer Standard.
The DEI1044 IC includes two TEST inputs for built in system test. They force the outputs of all receivers to the specified ZERO,
ONE or NULL state. The ARINC inputs are ignored when the device is in test mode. The DEI1045 does not have TEST inputs.
The DEI1044/1045 Quad Line Receiver can be used in conjunction with Device Engineering’s family of avionics products in
interfacing the ARINC 429 data bus.
