The DEICO MIL-STD-1553 In-Line Bus Coupler series offers various termination options for professional data bus architectures. It connects multiple stub terminals with defined impedance and transformer coupling.
Typical applications for the bus coupler series include avionics systems, military platforms, and test systems.
The DEICO DE80033XX is an aeronautical in-line bus coupler with 3 stubs, bus lines on the same side, and left-side termination, as shown in the variant overview. Compared to the DE80023XX, it differs in its termination side, while maintaining the same number of stubs and same-side bus routing.
