描述 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.
