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. 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). 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. · · · · · · Compliant to MIL-STD-1553A and B, MIL-STD-1760 and ARINC 708A 3.3V single supply operation Smallest footprint available in 7mm x 7mm 44 pin plastic chip-scale package (QFN) Less than 0.5W maximum power dissipation Industrial and extended temperature ranges Industry standard pin configurations October 2009 (DS1579 Rev.
