... 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-1567) or logic 1 (HI- 1568). 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 ...

... CMOS/TTL data at the RXA/B and output pins. Each set of receiver outputs can be independently forced TXA logic "0" (HI-1567) or logic “1” (HI-1568) by setting RXENA or RXENB low. BUSA MIL-STD-1553 BUS INTERFACE A direct coupled interface (see Figure 2) uses a 1:2 ...
