The HI-6110 is a CMOS integrated circuit implementing the MIL-STD-1553 (1553) data communications protocol between a host processor and a dual redundant 1553 data bus. The single chip architecture has a digital section containing all necessary logic and memory to process and store the command and data words for one complete 1553 message. The analog section includes dual transceivers coupled to the 1553 buses through external current mode transformers. The device is available in an industry standard 64-pin 9 mm square LPCC package, making it the smallest dual redundant 1553 interface product on the market.
