HI-1569

MIL-STD-1553 / 1760

5V Monolithic Dual Transceiver

DESCRIPTION

FEATURES

The HI-1569 is a low power CMOS dual transceiver

designed to meet the requirements of MIL-STD-1553

/1760 specifications.

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.

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.

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.
