The HI-15700 is a low power CMOS dual +5V transceiver with the ability to vary the amplitude of the transmitter outputs. It is designed to meet the requirements of the MIL-STD-1553 / 1760 specifications. It is a form, fit and function drop-in replacement for Holt’s HI-1570 MIL-STD-1553 transceiver.


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. A single pin allows the user to control the transmitter output amplitude. 


The receiver section of 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“.


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. For designs requiring independent access to transmitter and receiver 1553 signals, please contact your Holt Sales representative.
