HI-1565, HI-1566
MIL-STD-1553 / 1760
5V Monolithic Dual Transceivers
July 2009
DESCRIPTION
PIN CONFIGURATIONS
The HI-1565 and HI-1566 are low power CMOS dual
transceivers designed to meet the requirements of the
MIL-STD-1553 /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 each bus converts the 1553 bus bi-
phase differential data to complementary CMOS / TTLdata
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-1565) or
logic 1 (HI-1566).
44 Pin Plastic 7mm x 7mm
Chip-scale package
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.
