MIL-STD-1553: Aircraft Internal Time Division Command/Response Multiplex Data Bus
MIL-STD-1553 contains requirements for aircraft internal time division command/response multiplex data bus techniques which will be utilized in systems integration of aircraft subsystems. Even with the use of this standard, subtle differences will exist between multiplex data buses used on different aircraft due to particular aircraft mission requirements and the designer options allowed in this standard. The system designer must recognize this fact and design the multiplex bus controller hardware and software to accommodate such differences. These designer selected options must exist, so as to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architecture redundancy, degradation concept and traffic patterns peculiar to the specific aircraft mission requirements.
MIL-STD-1553B is current version of this standard which supersedes MIL-STD-1553A.
This standard establishes requirements for digital, command/response, time division multiplexing (Data Bus) techniques on aircraft. It encompasses the data bus line and its interface electronics and also defines the concept of operation and information flow on the multiplex data bus ana the electrical and functional formats to be employed.
