Rapid changes in the capabilities and complexities of avionic systems, along with the increasing dependency on these systems, mandates that the basic capabilities of the digital data bus system should be upgraded to match those of the using systems. Past methods of point to point wiring (unidirectional) results in higher wire count, higher wire weight and higher manufacturing costs. Boeing is developing a totally new airplane, utilizing technologies never before available on jetliners. Data transfer is required for the fly-by-wire, throttle by wire control, Avionics intercommunication, remote sensor implementation and remote control of many aircraft systems. Boeing has developed an advanced digital bus (DATAC) which has all the primary characteristics required for use in an advanced commercial transport airplane. The DATAC bus is a high speed bidirectional data bus which operates autonomously and is independent of any specific LRU. It is the result of over 40 man years of research and development at the Boeing Company. NEC has undertaken the design, manufacture and distribution of a CMOS LSI terminal in a single chip implementation.
