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.
