HI-1579, HI-1581

MIL-STD-1553 / 1760

3.3V Monolithic Dual Transceivers

October 2009

DESCRIPTION

PIN CONFIGURATIONS

The HI-1579 and HI-1581 are low power CMOS dual

transceivers designed to meet the requirements of the

MIL-STD-1553 specification.

BUSB

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.

BUSB 11

The receiver section of the each bus converts the 1553 bus

bi-phase differential 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-1579) or

logic 1 (HI-1581).

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.
