3.3V MIL-STD-1553/1760 Dual Transceiver

with Integrated Transformers

October, 2012

GENERAL DESCRIPTION

PIN CONFIGURATION (TOP)

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.

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^oC to

+85^oC, or Extended, -55^oC to +125^oC temperature

ranges.
