描述 Description

The DEI1116/DEI1117 provides an interface between a standard avionics type serial digital data bus and a 16-bitwide digital data bus. The interface circuit consists of a single channel transmitter with an 8X32 bit buffer, two independent receive channels, and a host programmable control register to select operating options. The two receiver channels operate identically, each providing a direct electrical interface to an ARINC data bus.
