GENERAL DESCRIPTION
The DEI3093 is an ARINC 429 transceiver (2RX/1TX) CMOS integrated circuit. It provides the interface between an ARINC 429 avionics data bus and a Serial Peripheral Interface (SPI) enabled host such as a microcontroller or ASIC. The four SPI control/data signals are CMOS/TTL compatible. The IC operates from a single 3.3V power supply.
