The CT1611 provides a complete Bus Controller and Remote Terminal interface between the MIL-STD-1553B chip set (CT1561, CT1602, CT1610, etc.) and most microprocessor-based systems (F9450A, 68000, 8086, VME bus, Multibus, etc.). The unit is constructed totally with CMOS technology and includes a custom CMOS chip, two HC CMOS FIFO's and HCT CMOS buffers. Thus the interface has extremly low power requirements. The CT1611 interface permits the use of all 15 mode codes and all types of data transfers as specified in MIL-STD-1553B in both Bus Controller and Remote Terminal operating modes. A Remote Terminal is capable of switching to a Bus Controller when requested via the Dynamic Bus Control mode code.
