HI-1567 Datasheet PDF - Holt Integrated Circuits

DESCRIPTION
The HI-1567 and HI-1568 are low power CMOS dual transceivers designed to meet the requirements of MIL-STD-1553 and MIL-STD-1760 specifications.
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 can be used to force the output of the receiver to a logic 0 (HI-1567) or logic 1 (HI-1568).
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.
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.
