8.6. Three-Level (3L) Input Pins (With External Resistors)

Figure 56. Three Level Input Pins



Any resistor pack may be used.



The Panasonic EXB-D10C183J is an example.



PCB layout is not critical.



Resistor packs are only needed if the leakage current of the external driver exceeds the listed currents.



If a pin is tied to ground or Vdd, no resistors are needed.



If a pin is left open (no connect), no resistors are needed.
