The Holt HI-15650 and HI-15660 are low power CMOS dual transceivers designed to meet the requirements of MIL-STD-1553/1760 specifications. They are form, fit and function drop-in replacement for Holt’s HI-1565 / HI-1566 and HI-1567 / HI-1568 / HI-1578 families of MIL-STD-1553 / MIL-STD-1760 transceivers.
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 inhibits control signals are provided for each transmitter.
The receiver section of each channel converts the 1553 bus bi-phase data to complementary 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 0 (HI-15650) or logic 1 (HI-15660).
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.
