Meeting safety-critical requirements with MIL-STD-1553
By George Los, Data Device Corporation
MIL-STD-1553, which has served as the primary command and control interconnect in military aircraft for more than 3 decades, is now being designed-in as the standard for next-generation commercial aircraft, thanks to its performance, reliability and safety.
MIL-STD-1553 is a protocol standard that defines the electrical and functional characteristics of a serial data bus that has been mainly used in military aircraft. The 1553 standard describes the method of communication, the data bus requirements, and the electrical interface requirements for the data bus. The bus architecture of MIL-STD-1553 allows for reduced size and weight of systems and the wiring that interconnects them, is inherently reliable and incorporates redundancies that make it a safe data bus solution. MIL-STD-1553A was published in 1975 and later revised in 1978 to MIL-STD-1553B, and has since served as the primary command and control interconnect in military aircraft. The performance, reliability and safety that made MIL-STD-1553 the standard for military aircraft for more than 3 decades is now being designed-in as the standard for next-generation commercial aircraft...
