FUNCTIONAL DESCRIPTION

The DEI1049 is a BiCMOS device which contains eight differential line receivers. Each receiver channel translates

incoming ARINC 429 data bus signals (tri-level RZ bipolar differential modulation) to a pair of TTL/CMOS logic

outputs. Each channel operates independently and meets the requirements of the ARINC 429 Digital Information

Transfer Standard. Refer to Figure 1 DEI1049 Block Diagram and Truth Table.
