7.6. 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.
Parameter Symbol Min Max
Input Low Current Iill –30 µA —
Input Mid Current Iimm –11 µA –11 µA
Input High Current Iihh — –30 µA
Note: The above currents are the amount of leakage that the 3L inputs can tolerate from an external
driver.
