HI-1569

HI-1569 August 2006 MIL-STD-1553 / 1760 5V Monolithic Dual Transceiver FEATURES DESCRIPTION The HI-1569 is a low power CMOS dual transceiver designed to meet the requirements of MIL-STD-1553 /1760 specifications. The transmitter section of each channel takes complementary CMOS / TTL digital input data and converts it to bi-phase Manchester encoded 1553 signals suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter. The receiver section of each channel converts the 1553 bus bi-phase data to complementary CMOS / TTL data suitable for inputting to a Manchester decoder. Each receiver has a separate enable input which can be used to force the output of the receiver to a logic 0. The transmitter outputs and receiver inputs for each channel are brought out to separate sets of pins. For typical MIL-STD-1553 applications the transmitter output and receiver input will be tied together at the isolation transformer. ! Compliant to MIL-STD-1553A & B, MIL-STD-1760, ARINC 708A !
