Any resistor pack may be used.

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 V
If a pin is left open (no connect), no resistors are needed.
The Panasonic EXB-D10C183J is an example.
PCB layout is not critical.
