HI-1565, HI-1566
MIL-STD-1553 / 1760
5V Monolithic Dual Transceivers
DESCRIPTION
FEATURES
PIN CONFIGURATIONS
The HI-1565 and HI-1566 are low power CMOS dual
transceivers designed to meet the requirements of the
MIL-STD-1553/1760specifications.
The transmitter section of each channel takes
complementary CMOS / TTL digital input data and
converts it to bi-phase Manchester encoded 1553 signals
suitablefordrivingthebusisolationtransformer. Separate
transmitter inhibit control signals are provided for each
transmitter.
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 (HI-1565) or
logic1(HI-1566).
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
eachcouplingtransformer.
