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.

FEATURES
● Quad ARINC 429 to TTL/CMOS logic line receivers
● Drop-in replacement for DEI1044 / DEI1045
