DEI1045A-TES-G
The DEI1044A and DEI1045A 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 requirements of the ARINC 429 Digital Information Transfer Standard.

Attributes
Functional Description The DEI1044A and DEI1045A 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 requirements of the ARINC 429 Digital Information Transfer Standard. The DEI1044A 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 DEI1045A does not have TEST inputs. The DEI1044A/1045A Quad Line Receiver can be used in conjunction with Device Engineering’s family of avionics products in interfacing the ARINC 429 data bus.
