Description

The HI-1567 and HI-1568 are low power CMOS dual transceivers designed to meet the requirements of MIL-STD-1553/1760specifications.

The transmitter section of each channel takes complimentary CMOS / TTL digital input data and converts HI-1567 and HI-1568  to bi-phase Manchester encoded 1553 signals suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter.

Thereceiver sectionof theeachchannel converts the1553 bus bi-phase data to complimentary 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 HI-1567 and HI-1568 .
To minimize the package size for this function of HI-1567 and HI-1568 , 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, pleasecontact your Holt Salesrepresentative.
