DESCRIPTION
The HI-1579 and HI-1581 are low power CMOS dual
transceivers designed to meet the requirements of the
MIL-STD-1553 specification.
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 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 the output of the receiver to a 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.
