The HI-15690 is a low power CMOS transceiver designed to meet the requirements of the MIL-STD-1553 and MIL-STD-1760 specifications.

The transmitter section takes complementary CMOS / TTL Manchester II bi-phase data and converts it to differential voltages suitable for driving the bus isolation transformer. A transmitter inhibit control signal is also provided for the transmitter.

The receiver section converts the 1553 bus bi-phase data to complementary CMOS / TTL data suitable for input to a Manchester decoder. The receiver has a separate enable input, which may be used to force the receiver output to logic "0". 

The HI-15690PCx is housed in a 32-pin plastic leadless chipcarrier package (QFN) with an integral exposed heatsink on the package bottom. The heatsink may be soldered to the PCB ground plane for optimal thermal dissipation. 


The QFN package version is a drop-in replacement for the Data Device Corporation BU-63155L3 transceiver and the ceramic DIP version is a drop-in replacement for the DDC BUS-63105 and BUS-63106 transceivers..
