GENERAL DESCRIPTION
The HI-2579 / HI-2581 are low power CMOS dual
transceivers with integrated transformers designed
to meet the requirements of the MIL-STD-1553 /
MIL-STD-1760 specifications. The dual transceivers with
integrated transformers provide a single part solution for
interfacing a protocol IC or FPGA to a dual redundant
MIL-STD-1553 bus.
The transmitter section of each bus takes complementary
CMOS / TTL Manchester II bi-phase data and converts it
to differential voltages suitable for driving the integrated
isolation transformer. Separate transmitter inhibit control
signals are provided for each transmitter.
The receiver section of the each bus converts the 1553
bus differential 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 both receiver outputs to logic “0” (HI-2579) or
logic 1 (HI-2581).
The family of parts are available in Industrial -40 C to
