... 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“. 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 ...

... CONT In a transformer coupled interface (see Figure 3), the transceiver is connected to a 1:1.79 isolation transformer which in turn is connected to a 1:1.4 coupling transformer. The transformer coupled method also requires two TXA B / are ei- coupling resistors equal to 75% of the bus characteristic impedance (Zo) between the coupling transformer and the bus ...
