... March 2003 DESCRIPTION The HI-1569 is a low power CMOS dual transceiver designed to meet the requirements of MIL-STD-1553 /1760 specifications. The transmitter section of each channel takes complementary CMOS / TTL digital input data and converts it to bi-phase Manchester encoded 1553 signals suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter ...
