... An example of termination resistance connection when the HD26LS31 is used as a balanced differential type driver is shown. Figure 2 Output Stage Circuit Configuration When termination resistance RT is connected between the two transmission lines, as shown in figure 7 the current path situation is that current IOH on the side outputting a high level (in this case, the Y output) flows to the side outputting a low level (in this case, the Z output) via RT, with the result that the low level rise is large ...
