Abstract: Based on common CMOS technology, designed an ARINC 429 Line Receiver. The device is designed to operate from either a 5 V or 3.3 V supply. Its receiver channel translates incoming ARINC 429 date bus signals to a pair of TTL/CMOS outputs. The test signals force the receiver output to the specified ZERO, ONE or NULL state. This circuit had been realized in the SMIC 0.18 μm HV LDMOS technology and reached the design request. It has high performance and strong commodity, already applied in an aeronautical communication system.

Key words: ARINC429, reference, comparator
