HI-1567, HI-1568
MIL-STD-1553 / 1760
5V Monolithic Dual Transceivers
May 2003
DESCRIPTION
PIN CONFIGURATIONS
The HI-1567 and HI-1568 are low power CMOS dual
transceivers designed to meet the requirements of
MIL-STD-1553 /1760 specifications.

The transmitter section of each channel takes
complementary CMOS / TTLdigital input data and converts
it to bi-phase Manchester encoded 1553 signals suitable
for driving the bus isolation transformer. Separate
transmitter inhibit control signals are provided for each
transmitter.

The receiver section of the each channel converts the 1553
bus bi-phase 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-1567) or
logic 1 (HI-1568).
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. For designs requiring
independent access to transmitter and receiver 1553
signals, please refer to the HI-1569 data sheet.
