    HD26C31 Line Driver Applications  
    The HD26C31 is a line driver that meets the EIA RS-422A conditions, and has been designed to supply a  
    high current for differential signals to a bus line. Its features are listed below.

    •
    Operates on a single 5 V power supply.  
    High output impedance when power is off  
    Sink current and source current both 20 mA  
    On-chip power up/down protection circuit  
    As shown by the logic diagram, the enable function is common to all four drivers, and either active-high or  
    active-low can be selected.  
    The output section consists of two output stages (the Y side and Z side), each of which has the same sink  
    current and source current capacity.  
    Connection of a termination resistance when the HD26C31 is used as a balanced differential type driver is  
    shown.

    Figure 2 IOL vs. VOL Characteristics  
    When termination resistance RT is connected between the two transmission lines, as shown in figure 3 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 R , with the result that the low level rise is  
    T
    large.  
    If termination resistance RT is dropped to GND on both transmit lines, as shown in figure 4 the current path  
    situation is that the current that flows into the side outputting a low level (in this case, the Z output) is only  
    the input bias current from the receiver. As this input bias current is small compared with the signal  
    current, it has almost no effect on the differential input signal at the receiver end.  
    Figure 5 shows the output voltage characteristic when termination resistance RT is varied.  
    Also, when used in a party line system, etc., the low level rises further due to the receiver input bias  
    current, so that it is probably advisable to drop the termination resistance to GND.  
    However, the fact that it is possible to make the value of RT equal to the characteristic impedance of the  
    transmission line offers the advantage of being able to hold the power dissipation on the side outputting a  
    high level to a lower level than in the above case.  
    Consequently, the appropriate use must be decided according to the actual operating conditions  
    (transmission line characteristics, transmission distance, whether a party line is used, etc.).  
    Figure 6 shows the output characteristics when termination resistance RT is varied.

    Figure 5 Termination Resistance vs. Output Voltage Characteristics  
    A feature of termination implemented as shown in figure 7 is that power dissipation is low when the duty of  
    the transmitted signal is high.  
    However, care is required, since if RT is sufficiently small, when the output on the pulled-up side goes high,  
    a large current will flow and the output low level will rise.  
    Figure 8 shows the output characteristics when termination resistance RT is varied.
