The HI-15691 is a low power CMOS dual transceiver designed to meet the requirements of the MIL-STD-1553 and MIL-STD-1760 specifications.


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 may be used to force the receiver outputs to logic "0". 


The HI-15691 is housed in a 64-pin plastic quad flat pack (PQFP) and is a drop-in replacement for the Holt HI-1569 and the Data Device Corporation BU-63152G3 transceivers.
