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 each bus converts the 1553 bus biphase data to complementary CMOS / TTL data suitable for input 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-1567) or logic 1 (HI1568). To minimize the package size for this function, the transmitter outputs are internally connected to the r...
