It was originally designed as an avionic data bus for use with military avionics, but has also become commonly used in spacecraft on-board data handling (OBDH) subsystems, both military and civil, including use on the James Webb space telescope.
This overview is designed to complement the referenced MIL-HDBK-1553A document, which provides an excellent detailed review of the 1553 standard (MIL-HDBK-1553A Section 20 provides a summary of MIL-STD-1553B Notice 2). Commercially available chip-sets and interface cards (like Alta’s) “off load” the protocol processing (protocol engine) so the engineer’s primary concern is design ...

MIL-STD-1553B is the military specification defining a digital time division command/response multiplexed data bus. The 1553 data bus is a dual-redundant, bi-directional, Manchester II encoded data bus with a high bit error reliability.
The digital data bus was designed in the early 1970’s to replace analog point-to-point wire bundles between electronic instrumentation. The latest version of the serial local area network (LAN) for military avionics, currently known as MIL-STD-1553B, was issued in 1978.
