HI-1569
MIL-STD-1553 / 1760
5V Monolithic Dual Transceiver
August 2006
FEATURES
DESCRIPTION
The HI-1569 is a low power CMOS dual transceiver
designed to meet the requirements of MIL-STD-1553
/1760 specifications.
!
Compliant to MIL-STD-1553A & B,
MIL-STD-1760,ARINC 708A
The transmitter section of each channel takes
complementary CMOS / TTL digital 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.

CMOS technology for low standby power
Single 5V power supply
Less than 1.0W maximum power dissipation
Military processing options
The receiver section of 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.
Industry standard 64-pin PQFPpackage
The transmitter outputs and receiver inputs for each
channel are brought out to separate sets of pins. For typical
MIL-STD-1553 applications the transmitter output and
receiver input will be tied together at the isolation
transformer.
