HI-1579, HI-1581
MIL-STD-1553 / 1760
3.3V Monolithic Dual Transceivers
DESCRIPTION
The HI-1579 and HI-1581 are low power CMOS dual
transceivers designed to meet the requirements of the
MIL-STD-1553 and MIL-STD-1760 specifications.
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 bus isolation
transformer. Separate transmitter inhibit control signals are
provided for each transmitter.
The receiver section of the each bus converts the 1553 bus
bi-phase data to complementary CMOS / TTL data suitable
for input to a Manchester decoder. Each receiver has a
separate enable input, which forces the receiver outputs to
logic "0" (HI-1579) or logic 1 (HI-1581).
To minimize the package size for this function, the
transmitter outputs are internally connected to the receiver
inputs, so that only two pins are required for connection to
each coupling transformer.
